Solved How does inbreeding depression occur? A. Inbreeding

WebIn most species, including humans, inbreeding between close relatives is generally avoided because it often leads to offspring with lower fitness. This phenomenon, known as inbreeding depression, is well documented and appears to be caused by the expression of homozygous deleterious recessive mutations.
