Explain the inheritance mechanisms that produce these results and where applicable indicate the dominance relationship.
b. A species of bird may have feathered or naked feet. A female bird homozygous for feathered feet is crossed with a male bird homozygous for naked feet. All the male offspring have feathered feet and all the female offspring have naked feet. When the F1 offspring are crossed with each other, the resulting F2 are produced in the following ratios:
Males: 3 feathered : 1 naked
Females: 3 naked : 1 feathered
Explain the inheritance mechanism that produces these results and indicate the dominance relationship.
