Question

4. Short hair in rabbits is governed by a dominant gene (L) and long hair by its recessive allele (l). Black hair results from the action of the dominant genotype (B-) and brown from the recessive genotype (bb).

a). In crosses between dihybrid short, black and homozygous short, brown rabbits, what genotypic and phenotypic ratios are expected?

b). Determine the expected genotypic and phenotypic ratios in progeny from the cross LlBb x Llbb.

Hi, Can you please explain clearly. Thank you.
