The images below represent the possible meiotic products produced in the woman’s  (from the Q above) germline.  Which of the four gametes, when fertilized by a normal sperm, would give rise to a zygote that has partial trisomy 21?  (white = chromosome 3, black = chromosome 21)

Colorblind 1 Your next project is to genetically map the locus for color blindness, an 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]
