Question

Short hair in hamsters is governed by a dominant gene L and long hair by the recessive allele l . Black hair results from the dominant genotype B_ and brown hair from bb (A) In a cross between a true breeding short haired, black hamster and a true breeding short haired, brown hamster what genotype and phenotypic ratios are expected among their progeny? (B) For the following cross LlBb X Llbb, what are the phenotypes of the hamsters (i.e. the parents), what genotypes and phenotypes would you expect in their progeny and in what ratios?
