Question

1. In cats, a sex-linked recessive allele, d, results in dystrophin-deficient muscular dystrophy. Its dominant counterpart, D, results in normal levels of dystrophin in muscle. Also, the dominant allele F at an autosomal locus is responsible for polydactyly (the presence of extra digits on each foot) and the expression of its recessive counterpart f results in the absence of polydactyly (having the 5 digits per front paw, and 4 digits per hind paw). A healthy female cat that has polydactyly gives birth to a male kitten with the normal number or toes. In addition, this male kitten has muscular dystrophy. What can you conclude about the genotype of: Unknown alleles should be indicated with a “?"
