Chickens have different comb morphologies which can be walnut,pea, single or rose. Suppose that a walnut combed hen is crossedwith a single combed roster; the F1 progeny all have walnut combs.These are then crossed to each other and the F2 progeny are: 93walnut, 11 single, 29 rose, 32 pea.
A) How is comb morphology inherited?
B) What would the progeny be if you crossed a homozygous rosecombed hen with a homozygous pea combed roster? What are thephenotypic ratios that you would see in the F2 progeny?
C) If a walnut rooster is crossed to a pea hen and the progenyare 12 walnut, 11 pea, 3 rose and 4 single, what are the genotypesof the parents?
D) If a walnut rooster is crossed to a rose hen and all theprogeny are walnut, what are the genotypes of the parents?
