WebJan 28, 2024 · Its impact on survival is not easily generalized. For a long-lived species such as gorillas, the overall impacts of inbreeding might take decades to manifest and are difficult to study. As inbreeding increases, harmful mutations typically become more and more concentrated in the population. Typical coancestries between relatives are as follows: Father/daughter or mother/son → 25% ( 1⁄4) Brother/sister → 25% ( 1⁄4) Grandfather/granddaughter or grandmother/grandson → 12.5% ( 1⁄8) Half-brother/half-sister, Double cousins → 12.5% ( 1⁄8) Uncle/niece or aunt/nephew → 12.5% ( 1⁄8) ...
