(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

Hope this is helpful!!!;))))
The F1 generation differed from the F2 in the Mendel's experiments in that all the F1 generation showed the dominant phenotype, however only three- fourths or three quarters of the F2 generation did. This is because all the F1 generation were heterozygous and thus the dominant phenotype was expressed, while in the F2 generation there was a mixture of homozygous dominant, homozygous recessive and heterozygous. Therefore, the heterozygotes and the homozygotes dominant showed a dominant phenotype.
Is the question multiple choice?
