Mendelian Genetics,BIOLOGY

A 03: Mendelian Genetics Name:Normally, in humans, brown eyes are dominant to blue.a) If two blue-eyed people have children, what percentage would you expect to have brown eyes?b) A child has blue eyes and his parents have brown eyes. What is the genotype of each parent?c) If a brown-eyed woman whose mother had blue eyes and whose father had brown eyes marries a blue-eyed man, what would you expect the phenotypes of their children to be? Can you figure out the genotype of the woman’s brown eyed father?In peas, green pods are dominant over yellow. What phenotypic ratio would you expect in the offspring from a cross between a heterozygous green pod plant and a plant with yellow pods?Caucasian humans have a gene which determines the curliness of hair. Individuals with straight hair are homozygous for the straight allele while those with curly hair are homozygous for the curly allele. Heterozygotes have wavy hair.If two wavy haired people mate, what phenotypes and genotypes would you expect among their offspring?If ALL of the many children of another couple have wavy hair, what would the most likely genotypes of the parents be?If a person with blood type AB marries someone with type O, what would be the possible genotypes and phenotypes of their children?A woman has blood type A. She marries a type B man. Their four children are: AB, AB, A, and A. Husband # 1 dies, and she marries Husband #2. They have two type A children. Then she gets divorced and marries Husband #3, who is type O. Their four children are all type A. What are the possible genotypes of all individuals?Woman:Husband #1: All four children from 1st marriage?: Husband #2:Both children from 2nd marriage?Husband #3:All four children from 3rd marriage? Show me a family tree for the first family in question 5, and two Punnett squares you used to figure out the genotypes.
