Answer the question
1. Progressive retinal atrophy (PRA) is a recessive disorder that causes blindness in Labrador retrievers. These dogs also have a gene that determines whether they have black hair (B) or brown hair (b). A breeder mates a brown Labrador retriever that is a carrier for PRA with a heterozygous, black Labrador retriever that does not carry PRA. What percentage of their offspring are predicted to have brown coats and not carry PRA? Use a Punnett Square/ Dihybrid Punnett

You are working with two forms of progressive retinal atrophy (PRA) in dogs--one form in Siberian Huskies, which is a sex-linked recessive allele, and one form in Labs, which is an autosomal recessive. Each breed is normal for the disease allele in the other breed. Assume you mate a Siberian male with the disorder to a female Lab with the disorder. (Assume homozygosity for the normal allele.) A) What is the phenotypic distribution of the progeny from this mating (include...
