How common is inbreeding in the wild
Discussion. We found that statistically significant levels of inbreeding depression in the wild are detected ≈54% of the time when species are known to be inbred. When significant, mean inbreeding depression (not corrected for the coefficient of inbreeding, F) ranged from 0.20 in poikilotherms to 0.51 in homeotherms.
How close is inbred
Close inbreeding is the mating of close relatives. The closest form of inbreeding in domestic animals involves matings between full brothers and sisters (full siblings) and between parents and offspring (collectively called first-degree relatives).
