WebThe seeds that can’t disperse very far mean only limited genetic diversity in the genome’s maternal portions. Genetic drift is a mechanism of evolution responsible for random … WebThe fluctuation in gene frequencies due to the random transmissions of genes is referred to as genetic drift [ 14, 15] or the founder effect [ 4 ]. The standard formulation of genetic drift by the Wright-Fisher model (or the alternative model of Moran [ 16 ]) is not applicable for tracking the viral population.

The founder effect is a case of genetic drift caused by a small … WebA founder effect is a form of genetic drift that takes place when a small number of individuals becomes isolated from a larger population and creates a new population in a distant area. This causes a change in the genetic makeup of the new population. The difference between founder effects and bottleneck events is that founder effects …
