A man who is a dwarf with achondroplasia and normal vision marries a color-blind woman of normal height. The man's father was average height, and both the woman's parents were of average height. A) Dwarfism caused by achondroplasia is autosomal dominant, which means the gene is carried on a non-sex chromosome . B) Red-green color blindness is X-linked recessive, which means that in female offspring, [ Select ] the gene is carried on the Y chromosome the gene must have both recessive alleles to be expressed in the phenotype the gene is carried on a non-sex chromosome the recessive allele is actually dominant .
