How do we measure genetic variation
WebMay 20, 2024 · Genetic variation is the presence of differences in sequences of genes between individual organisms of a species. It enables natural selection, one of the primary forces driving the evolution of life.

WebSep 29, 2024 · It is often measured as a fraction of the total variance for the trait that is genetic. The equation can be given as: H = V G / V P where H stands for heritability. It should be noted that here H does not define the fraction that is genetically determined but the fraction of the variability that is genetic.
