The pedigree below shows the transmission of albinism (absence of skin pigment) in a human family. 123 123456789 a. What is the most likely mode of transmission of albi- nism in this family? b. Using allelic symbols of your choice, identify the geno- types of the male and his two mates in generation I. c. The female I-1 and her mate, male I-2, had four children, one of whom has albinism. What is the probability that they could have had a total of four children with any other outcome except one child with albinism and three with normal pigmentation? d. What is the probability that female I-3 is a heterozygous carrier of the allele for albinism? e. One child of female I-3 has albinism. What is the prob- ability that any of the other four children are carriers of the allele for albinism?
