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.
