The black moss rabbit, heterozygous for both traits, is crossed with the same rabbit. determine the phenotype

The black moss rabbit, heterozygous for both traits, is crossed with the same rabbit. determine the phenotype and genotype of the offspring.

In conditions of complete dominance, a heterozygous individual demonstrates a dominant trait in the phenotype, from which the conclusion follows: in rabbits, black fur color dominates over white, and shaggy fur over smooth fur.

Let’s designate the gene for black rabbit fur as K, then the gene for white fur will be k.

Let’s designate the shaggy fur gene as L, then the smooth fur gene will be designated as l.

The diheterozygous black furry rabbit has the KkLl genotype and produces eggs of the following four types – kl, KL, kL, Kl.

She crosses with the same black hairy diheterozygous rabbit with the KkLl genotype, which produces spermatozoa kl, KL, kL, Kl.

The offspring of these rabbits will include the following options:

rabbits with shaggy black fur (4 KkLl, KKLL, 2KkLL, 2KKLl) – 56, 25%;

rabbits with smooth black fur (2Kkll, KK ll) – 18.75%;

rabbits with smooth white fur (kkll) – 6.25%;

rabbits with shaggy white fur (kkLL, 2kkLl) – 18.75%.
