b. Two couples are heterozygous for genes that cause albinism, but each gene specifies a different enzyme in the biochemical pathway for skin pigment synthesis. Their children, thus, do not face a 25% risk of having albinism. Answer c. Clara has severe neurofibromatosis type I. She has brown spots on her skin and several large tumors beneath her skin. A gene test shows that her son has inherited the disease-causing autosomal dominant allele, but he has no symptoms. Answer d. Mateo, an apparently healthy 24-year-old basketball player, dies when his aorta ruptures. A younger brother is nearsighted and has long and thin fingers, and an older sister is extremely tall, with long arms and legs. The older sister, too, has a weakened aorta. All of these siblings have Marfan syndrome. Answer e. The B allele confers black coat color and the b allele brown coat color in Labrador dogs. When another gene, E, is inherited, the coat is golden no matter what the B phenotype is. A dog of genotype ee expresses the black phenotype. Answer
