3) (6 point question) The following figure is from a recent paper that documented the frequency of different alleles of the X-linked opsin genes in the bald uakaris. The allele:s are categorized by the peak of the absorption spectrum for each rhodopsin. 0.600- 0.400 0.200 0 35 543 550 555 556 562 allele Figure from http://rspb.royalsocietypublishing.org/content/283/1828/20160067 A) (2 points) What mutational mechanism explains the distinct wavelengths that are seen in this figure? B) (2 points) It is unusual to have so many different alleles in the population, what selection mechanism might allow all these alleles to be quite common in the uakaris population? hiowe ate coma m C) (2 points) In humans the mutation rate at the LM locus is much higher than at the S locus. What might explain this higher rate of mutation?

Explanation / Answer

a. Genomic rearrangement is the mutational mechanism.

b. This selection is owing to negative-frequency dependence selection. The other reason for the selection is because of overdominance.

c. LM locus is having high rate of mutation rate as compared to S locus, present on 3rd chromosome in human, as LM locus is consist of large number of microsatellites elements that are highly mutable.
