WebThe level of gene flow between two populations can vary. Populations of organisms that are not very mobile (that do not or cannot move great distances) will have a relatively low … WebThe original population may become less diverse as a result of losing one or more of its individuals. Similarly, the migrants are likely to make their new population more diverse through the introduction of new gene variants. There are many examples of populations evolving through gene flow. introducing sandy craneWebEvolution by gene flow (migration) makes two different populations more similar to each other Two different populations are often subject to different selective pressures and genetic drift, so they would be expected to have different allele frequencies. new movies made from books 2022

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.
