Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there isn’t genetic exchange anymore. In some cases, subpopulations living in ecologically distinct peripheral environments can exhibit genetic divergence from the re… WebPhenetics, popular in the mid-20th century but now largely obsolete, used distance matrix -based methods to construct trees based on overall similarity in morphology or similar observable traits (i.e. in the …
