Explanation:
(a) The alleles of white feathers and that of single-head combs are dominant while that of the dark feathers and small combs are recessive.
(b) 1/16 or 6.25%
<h3>Dihybrid crossing</h3>
Since all the offspring resemble their mother, it means the alleles that make up the traits of the mother are dominant over that of the father.
Assuming that:
Feathers color = F/f
Comb type = C/c
Genotype of mother = FFCC
Genotype of father = ffcc
FFCC x ffcc
FfCc
Crossing: FfCc x FfCc
Progeny
F_C_ = 9/16
ffC_ = 3/16
F_cc = 3/16
ffcc = 1/16
