Heterozygote advantage in theory when two populations of any sexual organism are separated and kept isolated from each other, the frequencies of deleterious mutations in the two populations will differ over time, by genetic driftit is highly unlikely, however, that the same deleterious mutations will be prevalent in both populations after a. Usually this means that the mutation had to have an advantage if it didn't, then like most neutral mutations, it would stay at some low level or disappear entirely but it is obviously still around and going strong. Single nucleotide polymorphisms (snps) additional markers • snps have a much lower mutation rate than strs - snps 1 mutation per 108 generations • primary advantage that snps have for forensics is the ability to genotype even a. Dna codes carrying instructions for creating a protein can sometimes be 'spelt' differently, although they specify the exact same sequence information to create that protein scientists have now shown that such mutations, called 'synonymous' mutations can have large effects on the evolution of organisms.

A mutation is a change in the genetic makeup of a living organism this change can either be beneficial or detrimental to the living organism. The new work underscores the complexity of human genetics, and how thin the boundary is between a genetic strength and a genetic liability scientists believe that many mutations now linked to diseases as far-ranging as cancer and manic-depression may turn out to have a respectable pedigree, having conferred unknown advantages on modern.
