Unformatted text preview: For her to be Rh-, she will have to receive a little r from both parents – 1/2 from mom, and 1 from dad. For her whole genotype, 1/4 X 1/2 = 1/8 6. Does MAMO2 appear to segregate as though tightly linked to any of the other loci we have considered today? To determine this you will need to compare MAMO2 with each trait. Yes, the MAM02 locus appears to be linked to the ABO locus. (You can rule out the two X-linked traits right away since males in the pedigree have 2 alleles for the MAM02 locus.) 7. On which chromosome is the MAMO2 locus? The ABO locus is on chromosome #9, so the MAM02 locus must be as well. 8. Does this information clarify Boris’ genotype at any locus? If so, show the clarification. When considering ABO information alone, we could not decide the full genotype for Boris (I A ?). Using the segregation of the MAM02 PCR alleles, we know that Boris is I A I A ....
