WebInbreeding is actually lower down the diversity of gene pool. This mean you will have genetic clones in a population when there is inbreeding. That mean this inbreed population lost the genetic diversity which is very much important for survival. For e.g. a single viral attack and entire population will be doomed.

Inbreeding increases homozygosity, which can increase the chances of the expression of deleterious or beneficial recessive alleles and therefore has the potential to either decrease or increase the fitness of the offspring. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes. The c… WebThe genetic underpinnings of inbreeding depression are best understood in Drosophila, in which recessive lethal mutations and mildly deleterious mutations are major causes. Gradual inbreeding permits natural selection to purge the former but the partially recessive near-neutral mutations continue to increase in frequency and significance.
