Genome 371 Spring, 2004 NAME: _ 2 Problem 1. (20 points) In this pedigree, colorblindness is represented by horizontal hatching, and is determined by an X-linked recessive gene (g); the dominant allele for color-vision is (G). Hemophilia is represented by vertical hatching and is determined by the X-linked recessive gene (h); the dominant allele for normal blood clotting is (H). (a). What is the genotype of the female in generation 2. Show the arrangement of alleles on the X- chromosomes below. (b). Indicate whether each child in the third generation received a parental combination of alleles (with a P) or a recombinant combination of alleles (with an R) from the mother. If it cannot be determined, indicate with a (?) (c). When the husband walks in on his wife and the mailman, he becomes so infuriated that he immediately files for divorce and takes his three kids to live in another state with him; he forbids his three children to see or even talk with their cheating mother. The mother, finding out during the divorce trial that she is pregnant with the mailman’s child, rushes to marry him. Together, the new couple has a total of two children (as shown in the above pedigree). Yet, the mother and mailman’s always keep the secret of the mother’s previous family from their children. However, when the female child (offspring of the mother and the mailman/2nd husband) meets the colorblind male (offspring of the mother and her first husband) at college, they fall in love, elope, and are currently expecting their first child. What is the probability that this child will be colorblind? What is the probability that this child will have hemophilia? P, R, or ?: ___ ___ ___ ___ ___ mailman husband colorblind hemophilia both
