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 alleles are categorized by the peak of the absorption spectrum for each rhodopsin 0.600 0.400 0.200 535 543550555556 562 allele Figure from http://rspb.royalsocietypublishing.org/content/283/1828/20 160067 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? 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) in my opinion i think missense mutation has been occured. In this type of mutation, changes occur in one base pair of DNA instead of substituting amino acids. Since they are heterzygous changes might have occured on DNA base pair.
b)yes it is difficult for the selection process,,,but for that you can also perform restriction fragment length polymorphism, which will use selected common fragments in different alleles and perform polymorphisms in alleles, which will help in identifying different alleles of gene, and from which organism they belong.
c) mutation rate flows in both directions of centromere.
if it is near centromere, it is expected that recombination is suppressed. And if it is near telomere, it is expected that recombination rate is higher.In addition, loci near centromers have higher linkage disequilibrium than near telomers.
