WebI have heard it estimated that, in humans, every baby is born with around 60 unique mutations, many of which are deleterious. A carefully conducted program of inbreeding can be used to eliminate known recessive alleles, but you still generally see a loss of vigor over time due to accumulation of new or unknown recessive alleles. WebInbreeding depression - the reduced survival and fertility of offspring of related individuals - occurs in wild animal and plant populations as well as in humans, indicating that genetic variation in fitness traits exists in natural populations.
