Cоlоrblind 1 Yоur next project is to geneticаlly mаp the locus for color blindness, аn X-linked recessive trait, with respect to simple sequence repeat (SSR) markers. Like many X-linked recessive traits, colorblindness is usually found in males. However, the mutant allele frequency is sufficiently high that colorblind females do occur. In this problem, + is the allele that leads to normal vision, and clr is the allele associated with color-blindness. Assume complete penetrance and no new mutations. The family below has been genotyped for two SSR markers – there are 2 alleles for SSR 72 (Z&W) and 3 alleles for SSR 73 (a,b, & c). The mother is deceased; thus, her DNA has not been analyzed. Below the pedigree are the results from the DNA analysis – the heavier bands indicate more DNA. A) What is the (deceased) mother’s genotype at SSR72? [A] B) What is the (deceased) mother’s genotype at SSR73? [B] C) What is the most likely phase relationship between the alleles at SSR72 and the color blindness locus in the mother. [C] D) What is the most likely phase relationship between the alleles at SSR73 and the color blindness locus in the mother. [D]
