How does inbreeding affect genetic variation

WebThe severity of inbreeding and genetic variability loss can be reduced by immigration and/or ranching of a few individuals into a population—known as the rescue effect but in the absence of any such migrants, inbreeding depression may act as a driving force to put the populations to an extinction vortex.
