Question

youIn hamsters, the allele for black coat colour (B) is dominant over the allele for white coat colour (b) cross a hamster that is heterozygous black and homozygous rough with one that is heterozygous black and heterozygous rough, what will be the phenotypes and genotypes of the offspring?

Answer 1

The genotypes and phenotypes of the offspring will include black and rough, black and smooth.

Step-by-step explanation:

To determine the phenotypes and genotypes of the offspring, we can create a Punnett square using the given information. The hamster that is heterozygous black and homozygous rough can be represented as Bb RR, while the other hamster that is heterozygous black and heterozygous rough can be represented as Bb Rr. When we cross these two hamsters, the possible genotypes and phenotypes of the offspring are:

Genotypes:
Bb RR, Bb Rr, Bb Rr, Bb rr

Phenotypes:
Black and rough, black and rough, black and rough, black and smooth
