Events like natural disasters (earthquakes, floods, … WebGene flow is the migration of individuals between two populations of the same species. As long as individuals can move between the two populations, the populations remain as the same species because they are sharing genetic information - any new alleles (therefore traits) are passed between populations and they evolve together. WebJul 16, 2016 · Gene flow and the evolution of novel weeds and invasives. The evolution of novel weeds and invasives need not involve domesticates at all.

"WebGenetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck " - Genetic flow examples
