Gene diversity index
WebDec 9, 2024 · Figure 2 - (A) Genetic diversity is generated when mutations create new alleles over time. Mixing alleles from parents creates new combinations of alleles in their babies. Organisms that can clone themselves, like bacteria, can pass alleles to each other. Each coloured dot represents a different allele. http://agtr.ilri.cgiar.org/quantitative-methods/measuring-genetic-diversity-molecular-data

Recently, it was proposed as a unifying measure of diversity at different levels—from genes and populations to whole species and ecosystems. The index, however, was proven to be negatively biased at small sample sizes.
