In a certain breed of chicken, two genes control
color. A dominant allele (I) inhibits the expression of
any color gene (C). A second recessive gene (c)
results in albinism when homozygous (cc). Give the
F2 phenotypic ratio of a colored chicken ii CC with a
white II cc. What will be an ideal response?
Answer: 9 I__C__ + 3 I__ cc + 1 ii cc = 13 white + 3 ii C__ = 3
