Give the genotype of both parents and the son. PARENT 5. In cats, the allele (B) produces black color but (b) produces a yellow color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell color. The alleles (B) and (b) are sex-linked as well. Cross a tortoise shell female with a yellow male. a. What percent of their offspring will be yellow? b. What percent of their offspring will be black? c. What percent of their offspring will be tortoise shell? d. Why is it impossible to have a tortoise shell male offspring? PARENT
