Genetic Drift vs. Gene Flow vs. Natural Selection

WebOnce an allele becomes fixed, genetic drift comes to a halt, and the allele frequency cannot change unless a new allele is introduced in the population via mutation or gene flow. Thus even while genetic drift is a random, directionless process, it acts to eliminate genetic variation over time. Rate of allele frequency change due to drift WebDescribe different mechanisms of evolution, including natural selection, genetic drift, gene flow, and mutation. ... However, natural selection and genetic drift cannot operate unless there is genetic variation—that is, unless some individuals are genetically different from others.

The lack of gene flow also prevents the spread of adaptive genetic complexes. Speciation is unlikely in these fragmented isolates; rather, an extinction ratchet is created by the fragmentation.
