PUNNETT PRACTICE #2 1. In Four O’Clock plants, RED FLOWERS (R) are INCOMPLETELY dominant over white (r) flowers. Therefore, heterozygous plants show a blended intermediate phenotype of PINK flowers. MAKE A CROSS WITH 2 HETEROZYGOUS FOUR O’CLOCK PLANTS. POSSIBLE Offspring x __ __ Genotypes ______ ______ ______ __ Phenotypes _____________________ _____________________ _____________________ __ 2. If the red allele in Four-o’clocks was COMPLETELY DOMINANT over the white allele, what would the phenotype be for a plant with a Rr genotype? ______________________ * * * * * * * * * * * * * * * 3. You are exploring the jungle and find a new species of plant. Some of the plants have red flowers and some have yellow flowers. You cross a red flowering plant with a yellow flowering plant and all the offspring have orange flowers. You might assume that the alleles for flower color in this plant show: A. B. C. complete dominance incomplete dominance codominance 4. If the red and yellow alleles in the mystery jungle plant above showed CODOMINANCE instead, what might you expect a plant with one red allele and one yellow allele to look like? A. B. C. D. It It It It would have all red flowers would have all blue flowers would have red and yellow flowers together on one plant wouldn’t make any flowers because it is a mutant. BLOOD TYPES: In the ABO blood type system, A and B alleles are dominant. O alleles are recessive. A and B are CODOMINANT to each other. 5. Make a cross between a type AO mom and a type BO dad. What are the possible genotypes and probability (%) of each blood type of the offspring? POSSIBLE Offspring x __ __ __ __ * Genotypes ___ ___ ___ ___ ___ ___ ___ ___ Phenotypes blood type A = blood type B = blood type O = blood type AB = _____% _____% _____% _____% * * * * * * * * * * * * * * 6. Make a cross between a type AO mom and a type BB dad. What are the possible genotypes and probability (%) of each blood type of the offspring? POSSIBLE Offspring x __ __ __ Genotypes ___ ___ ___ ___ Phenotypes blood type B = _____% blood type AB = _____% __ * * * * * * * * * * * * * * 7. Make a cross between a type AA mom and a type OO dad. What are the possible genotypes and probability (%) of each blood type of the offspring? POSSIBLE Offspring x __ __ __ __ Genotypes ___ ___ Phenotypes blood type A = _____% Draw a picture of what the blood cells of these offspring would look like. 8. You are working in the Emergency room and a bleeding patient with type B blood is brought in. You need to give him blood, but the hospital is all out of type B. Circle ALL the types of blood you could safely give him instead. A AB O 9. What if the bleeding patient had type AB blood and the hospital was out of AB blood. Circle ALL the types of blood you could safely give him. A B O JERRY SPRINGER GENETICS Wanda tells Jerry Springer that she thinks either Ralph or Fred could be the father of her baby. Wanda’s genotype is AO. Ralph’s genotype is AB. Fred’s genotype is BO. Wanda’s baby has type O blood. Genotype = ___ ___ Make two crosses to show who could be the father of Wanda’s baby. Ralph X Wanda x __ __ Fred X Wanda x __ __ __ __ __ __ Is it possible for Ralph to be the baby’s father? YES NO Is it possible for Fred to be the baby’s father? YES NO Does this absolutely PROVE that Fred IS the baby’s father? YES NO EXPLAIN Your answer _________________________________________________ ___________________________________________________________________ Wanda’s baby has type O blood, so….what are the possible genotypes for men who COULD BE the father of Wanda’s baby? ____ ____, ____ ____, ____ ____ Just a little advice… Don’t put yourself in a situation where you ever might need to call this number.
