4, with chickens, hens (females) have one ..z” and one “w” sex chromosome, and roosters (males) have two “z” sex chromosomes. Let’s assume that in one variety of chicken, the gene for feather-color is Z-linked and exhibits incomplete dominance, where feathers can be either all white, all black, or all grey What is the genotype for a black hen? __ What is the genotype for a white hen? _ What is the genotype for a grey hen? _ For a black rooster? For a white rooster? For a grey rooster?H (A) What is the probability that a grey rooster and white hen produce a chick that grows up to be a hen with black feathers? Parents’ genotypes:-x Punnett square: ANSWER: (B) What is the probability that the same two parents produce an offspring that grows up to have white feathers? ANSWER: 5. In a certain species of butterfly, there is a wing-color gene for which the dominant allele, B, is required for black wings; the recessive allele, b, produces red wings. At a second gene, however, a dominant P allele inhibits any pigment formation and results in white wings, whereas the recessive p allele permits pigment deposition in the wings. (A) What are the phenotypes of the following parents? Genotype of Parent l = bbpp Genotype of Parent 2 BbPp Phenotype of Parent- Phenotype of Parent 2 = (B) What would be the phenotypic ratio of wing color among these two parents’ possible offspring?
