Question

3. In chickens, the white plumage of the leghorn breed is dominant over colored plumage, feathered shanks are dominant over clean shanks, and pea comb is dominant over single comb. Each of the gene pairs segregates independently. If a homozygous white, feathered, pea-combed chicken is crossed with a homozygous colored, clean, single-combed chicken and the F1are allowed to interbreed, what proportion of the birds in F2the will produce only white, feathered, pea-combed progeny if mated to a colored, clean

Answer 1

Answer:

all sub-questions carries equal grades): In chickens, the white plumage of the leghorn breed is dominant over colored plumage, feathered shanks are dominant over clean shanks, and pea comb is dominant over single comb. Each of the gene pairs segregates independently: If a homozygous white, feathered, pea- combed chicken is crossed with a homozygous colored, clean, single-combed chicken and the F1 birds are allowed to interbreed. What proportion of the birds in the F2 will produce only white, feathered, pea- combed progeny if mated to colored, clean-shanked, single-combed birds? (Use W/w for color, Flf for feather and P/p for pea comb. show the workflow to reach your answers)
