Question

HELP PLEASE I WILL GIVE BRAINLIEST AND THANKS

Answer 1

(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%

Dihybrid crossing

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
