Back • What are purines and prymidines? • Purines – Guanine & Adenine • Prymidines – Cytosine & Thymine • Classification of nitrogenous bases Back • What are the three scientists to help to discovery DNA and what did they contribute to the discovery? • Watson – Model of DNA • Crick – Model of DNA • Franklin - Helix Back • The forming of a Protein from mRNA is called… • Translation (different language) Back • The forming of mRNA from DNA is called … • Transcribing (same language) Back • What is a phenotype and genotype of an individual? • Phenotype – Physical traits • Genotype – Genes inside Back • Name 3 ways in which RNA is different from DNA. • Ribose Sugar • Single Stranded • Uracil Back • Describe how a trait is expressed from the DNA. (hint – mention the processes and the jobs of all 3 RNA’s) • mRNA is transcribed from DNA in the nuclues. mRNA travels out to the ribosome (rRNA) where it is translated into proteins. tRNA match the amino acids to the correct codon of the mRNA. Finally the amino acid chain is folded into a protein. Back • Who is the father of genetics? • Gregor Mendel Back • Each individual inherits one allele from Mom and one from Dad. This expresses which of the following Mendelain laws • Law of Segregation Back • Two mice with black fur were crossed and produced offspring with black fur and offspring with white fur. If black is dominate over white, what would represent the most probable genotypes of the parental mice? • Bb x Bb Heterozygous Back • In humans, dimples is completely dominant to no dimples. Two parents that are both heterozygous for dimples are expecting a child. What are the chances that the child will have dimples? Complete a punnett square. • 75% Back • What is best way to determine the phenotype of a guinea pig is to? • Observe it Back • A cross of a red flower with a white flower produces pink flowers. This is a type of inheritance called • In-complete Dominance Back • If a mothers blood type if AB and dad’s blood type is A (homozygous). Will Mom will be able to give blood to all of her children? • No. 50% of her children will have Type A and 50% will have Type AB Back • Human blood types is an example of ___________. Name the two types of dominance associated with the blood types. • Multiple Alleles • Co-Dominance & Complete Dominance Back • A woman carrying the gene for hemophilia marries a man who is a hemophiliac. What percentage of their children can be expected to have hemophilia? Complete Punnett Square • 50% Back • Co-Dominance. A black chicken and a white chicken produce a checked chicken. If two checkered chicken are crossed what is the phenotypic and genotypic ratios? Show your work using a Punnett square. • Pheno – B:C:W 0:2:2 • Geno - BB:BW:WW 0: 2 : 2 Back • What shapes represent males and females in a pedigree? • Square – Males • Circles - Females Back • True or False: Genetic counselors often help people with a family history of genetic disorders. Give an example. • True Back • Name three purposes of a pedigree. • To understand how traits are passed on • Identify disorders in future generations • Represent genetic relationships between family members Back • Identify the type of pedigree below: • Sex-Linked Back • Identify the type of pedigree below & give the genotype of individual I-1. • Autosomal Dominant • Heterozygous Back • Complete a Dihybrid of two heterozgous yellow round seeded pea plants. (yellow round seeds is dominant to green wrinkled seeds)
