Hyman, the star of the US Olympic volleyball team won the silver medal, later joined a Japanese professional team. In 1986, after leaving a party to take a short break, died while sitting quietly on the bench. How could this happen to someone just 32 years old and in excellent physical condition? Flo Hyman suffered from a genetic disorder called Marfan syndrome, which is surprisingly common and affects one in every 5,000 people. People with Marfan syndrome are usually tall and thin, with long limbs and unusually large hands and feet. These features helped Flo Hyman to become an outstanding volleyball player. Unfortunately, Marfan syndrome can also lead to death. The autopsy revealed that Hyman died of a rupture in the aorta, the large artery that carries blood from the heart to most of the body. Why aorta Hyman broke? What has in common a weak aorta with height and big hands? Marfan syndrome is caused by a mutation in the gene encoding a protein called fibrillin, forming long fibers give strength and elasticity to connective tissue. Many parts of the body contain connective tissue, including tendons, ligaments, and arterial walls. Defective fibrillin molecules weaken the connective tissue, sometimes with tragic consequences. Apparently, mutations in the fibrillin also stimulate growth, which makes people with Marfan syndrome are high and very thin. How did Flo Hyman acquire this condition? Is this syndrome inherited from her parents? Or was it a new mutation (perhaps in the DNA of her mother's egg or sperm from his father that fertilized)? Since new mutations are rare cases, we formulate the hypothesis that Hyman inherited a defective gene from their parents. Geneticists can do experiments in the usual sense, in humans; but also gather other evidence to help them identify ways in which inheritance is transmitted.What evidence is needed to determine whether Marfan syndrome Hyman was the result of a new mutation or if she inherited from her parents? If it was inherited, ¿came from both parents or could inherit only from one? If Hyman would have had children, they would be likely to have Marfan syndrome? ¿Flo Hyman suffered a new mutation or inherited Marfan syndrome? Medical tests revealed that her father and sister had Marfan syndrome, unlike her mother and brother. Does this finding proves that Hyman inherited the defective allele of the father? Diploid 3 [Escribir texto] organisms, including people generally have two alleles of each gene, one in each homologous chromosome. For many years it has been known that a defective fibrillin allele is sufficient to cause Marfan syndrome. Moreover, the children of a person with Marfan syndrome have a 50 percent chance of inheriting the disease. What can we conclude from these data? First, if only one defective allele defi -brilinaMarfan syndrome occurs, then Hyman's mother must have been carrying two normal alleles, because they had no such syndrome. Second, since new mutations occur rarely and father Hyman has Marfan syndrome, almost certainly inherited a defective allele Hyman fibrillin her father. Third, Marfansíndrome is inherited as a dominant or recessive condition? Again, if one defective allele is sufficient to cause Marfan syndrome, then this should be dominant allele and the normal allele must be recessive. Finally, if Hyman would have had children, would they have inherited from her Marfan syndrome? In the case of a dominant disorder, any child would inherit his defective allele developed Marfan syndrome. Therefore, on average, half of their children would have Marfan syndrome (try to figure this out with the Punnett square). Think about this. It is impossible to detect Marfan syndrome in an embryo by a simple biochemical test (so far). However, most mutations Cystic Fibrosis easily detect both homozygous and heterozygous, either adult, child or embryos. Some years ago, some US states considered making mandatory testing for cystic fibrosis couples wishing to marry. If two heterozygous marry, each of their children has a 25 percent chance of developing the disease. Although there is no cure, it is likely that better treatments are available in a few years. Do you think that the evidence to identify carriers should be mandatory? If you and your partner were heterozygous, would you make prenatal diagnosis of an embryo? What would you do if your embryo was destined to be born with cystic fibrosis? Answer the following questions 1- How is the genetic information of a generation transmitted to the next? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 2- What are genes? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 4 [Escribir texto] Quick Lab Feature A B C D E Dominant Trait Free ear lobes Hair on fingers Widow’s peak Curly hair Cleft chin Trait Survey Number Recessive trait Attached ear lobes No hair on fingers No widow’s peak Strait hair Smooth chin Number 1- Write a prediction of whether the trait listed in the table will be evenly distributed or if there will be more dominant than recessive traits. __________________________________________________________________________________ __________________________________________________________________________________ 2- Interview at least 14 other students to find out which trait they have. Record the totals in each column. __________________________________________________________________________________ __________________________________________________________________________________ 3- Calculate the percentage of each trait in your total sample.

Humans inherit genes from their parents. Children who exhibit a dominant allele such as freckles must receive the dominant allele from one of their parents. 5 [Escribir texto] Analyze and Conclude The following table shows some Mendelian traits exhibited by Julia and her parents.

La estructura genética de un individuo se conoce como genotipo. Las características físicas de un individuo, que son el resultado de su genotipo y su entorno, se conocen como fenotipo. Algunos alelos se manifiestan sólo cuando el genotipo es homocigótico. Se dice que estos alelos producen fenotipos recesivos. Los alelos que se manifiestan tanto si el genotipo es homocigótico o heterocigótico producen fenotipos dominantes. Un alelo que codifica para un rasgo dominante se representa con una letra mayúscula, mientras que un alelo que codifica para un rasgo recesivo se representa con una letra minúscula. Algunas veces, cuando el genotipo es heterocigótico, no se produce un fenotipo recesivo ni uno dominante. En esta situación, llamada dominancia incompleta, se produce un fenotipo intermedio. En los seres humanos, el sexo de un individuo está determinado por la combinación particular de dos cromosomas, llamados cromosomas sexuales. Los individuos que tienen dos cromosomas X (XX) son mujeres, mientras que los que tienen un cromosoma X y uno Y (XY) son hombres. En esta práctica observarás cómo diferentes combinaciones de alelos dan como resultado ciertos rasgos. Problema ¿Cómo se heredan los rasgos? Discusión previa Lee toda la práctica. Después trabaja con uno de tus compañeros para responder las siguientes preguntas. 1. ¿Qué representa uno de los dos lados de una moneda o de un disco? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 2. ¿Cuál es la probabilidad, en porcentaje, de que al lanzar una moneda al aire caiga cara? ¿Y de que caiga cruz? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 3. ¿Por qué el lanzamiento de una moneda es una buena manera de representar las combinaciones de alelos que ocurren en la naturaleza? 29 [Escribir texto] ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 4. Para todos los rasgos explorados en este laboratorio, ¿todos los pares de alelos heterocigóticos producen un fenotipo intermedio? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 5. ¿Puedes determinar con exactitud el genotipo de un organismo con sólo observar su fenotipo? Explica tu respuesta. ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ Materiales (por equipo) • 3 libros de texto • 2 monedas Procedimiento 1. Coloca los libros de texto en la mesa de laboratorio de manera que formen un triángulo. 2. Determina qué estudiante lanzará la moneda por la mujer y quién la lanzará por el hombre. Recuerda que son dos genes por rasgo. 3. Pide al compañero que represente al hombre que lance la moneda de manera que caiga dentro del triángulo para determinar el sexo del descendiente. Si cae cara, el descendiente es mujer; si cae cruz, es hombre. Registra el sexo del descendiente al inicio de la página anterior. 4. Ahora, todas las veces que lances la moneda, la cara representará el alelo dominante y la cruz el alelo recesivo. 5. Ahora tú y tu compañero deben lanzar las monedas dentro del triángulo al mismo tiempo para determinar el fenotipo del primer rasgo, la forma de la cara. (Nota: Sólo deben lanzar las monedas una vez para cada rasgo). 6. Continúen lanzando las monedas para cada rasgo listado en la tabla de la siguiente ilustración. Cada vez que lances la moneda, registra el rasgo de tu descendiente mediante una paloma en el cuadro correspondiente de la tabla. (Nota: Se ha simplifi cado alguna información de la ilustración. En realidad, algunos rasgos listados son producidos por dos o más genes). 7. Con los rasgos listados, dibuja las características faciales de tu descendiente en el espacio de la página anterior. 30 [Escribir texto] 31 [Escribir texto] 32 [Escribir texto] Sexo del descendiente ____________________________________________________________________ Dibujo del descendiente 33 [Escribir texto] Análisis y conclusiones 1. Inferir ¿Cuáles son los posibles genotipos de los padres de un descendiente que tiene cabello ondulado (Hh)? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 2. Predecir ¿Puedes predecir que otro par de estudiantes en tu clase tendrían un descendiente genéticamente idéntico al tuyo? Fundamenta tu respuesta. ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 3. Sacar conclusiones ¿Crees que alguno de tus compañeros de clase tiene los mismos rasgos genéticos que tú? Explica tu respuesta. ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 4. Comparar y contrastar ¿En qué es similar este modelo de lanzar la moneda a la manera en que los seres vivos heredan sus rasgos? ¿En qué es diferente el modelo? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 34
