Explain your answer. Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness. What is the genotype of a man with normal color vision whose father was color- blind?
