WebGenetic variation - the variation in genotypes (i.e. the genes) between species or within a species Phenotypic variation - the variation in phenotypes (i.e. anything other features apart from the genes) between species or within a species e.g. variation in height, mass, shape, colour, blood type Web12 feb. 2016 · We find evidence consistent with at least three genetic sources of adaptive variation: introgression among species, de novo mutation, and recruitment from ancestral variation. Our results indicate that a combination of all three of these evolutionary factors facilitated rapid adaptive expansion in response to ecological opportunity.
