3. A man who has polydactyly and normal vision marries a color-blind woman with a normal number of hand and foot digits. The man's father has normal hand and foot digitation, and both the woman's parents have normal hand and foot digitation. A) Polydactyly is autosomal dominant, which means [ Select ] a. the gene is carried on the X chromosome b. the gene is carried on a non-sex chromosome c. the gene is carried on the Y chromosome d. the dominant allele is actually recessive B) Red-green color blindness is X-linked recessive, which means that in females, [ Select ] the recessive allele is actually dominant b. the gene is carried on a non-sex chromosome c. the gene must have both recessive alleles to be expressed in the phenotype d. the gene is carried on the Y chromosome а. C) What proportion of their sons would be color blind and polydactyly? [ Select ] a. half b. none C. one out of four d. all
