The individuals that have these helpful mutations might have greater chances of survival, and have more babies as a result . ... Inbreeding: ↑ Breeding between closely related individuals. … WebInbreeding depression is thought to be caused primarily by the collection of a multitude of deleterious mutations, few in themselves fatal, but all diminishing fitness. Normally, in an outbreeding population these alleles would be selected against, hidden, or corrected by the presence of good alleles (versions of genes) in the population.

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. WebInterbreeding increases the probability of a child being born with a double dosage of one or more recessive genetic problems that can cause congenital birth defects. 40,000 to 30,000 years ago.
