Genetic diversity stability
WebEstimates of genetic variation for different species used in comparative studies vary widely in the number of sampled individuals and populations, and in the regions of the genome analyzed. Some studies estimate species-wide genetic diversity from a single individual (11, 95, 96) and compare different genetic data types across species (6, 96).
