Detailed explanation-1: -In rabbits, the gene for grey fur (G) is dominant over that for black fur (g). In a litter, if 50% rabbits are grey, then the possible parental cross combination is. GG x Gg.
Detailed explanation-2: -In rabbits the gene for grey fur (G) is dominant over that of black fur (g). In a litter, if 50% rabits are grey, the possible parental cross combination is.
Detailed explanation-3: -In rabbits, gray hair (G) is dominant to white hair (g), and black eyes (B) are dominant to red eyes (b). These two traits are independent of each other. In other words, a female rabbit with the genotype GgBb may produce eggs with the alleles GB, Gb, gB, or gb.
Detailed explanation-4: -So, one out of 9 black long fur progeny will be homozygous for both the genes.
Detailed explanation-5: -In rabbits, the B gene controls the color base of the coat. The B gene has two alleles: B and b. The B allele is considered the wild-type allele: it codes for black color. The b allele codes for chocolate (brown) color base.
