WebMeasuring Gene Expression. Small variations in our DNA can correlate with differences in the way individuals respond to a medication or in their risk for getting a disease. Often, these variations occur within the DNA … WebNucleotide diversity is a concept in molecular genetics which is used to measure the degree of polymorphism within a population. [1] One commonly used measure of nucleotide diversity was first introduced by Nei and Li in 1979. This measure is defined as the average number of nucleotide differences per site between two DNA sequences in all ...

Natural selection does not act on these neutral genes. Adaptive genetic diversity consists of genes that increase fitness and are responsible for adaptability to changes in the environment.
