Short Hair in Rabbits Is Produced by a Dominant Allele

Essay

Short hair in rabbits is produced by a dominant allele (l⁺)and long hair by its recessive allele (l).Black hair results from the action of a dominant allele (b⁺)and brown hair from its recessive allele (b).Determine the genotypic and the corresponding phenotypic ratios of the F₁ offspring,beginning with a parental cross of a rabbit with brown,short hair to a rabbit with long,black hair.Assume that the parent with short hair is homozygous for that allele,and that the parent with black hair is homozygous for that allele.Assume independent assortment.
