Weband little inbreeding due to factors such as social organization (which can subdivide the population and cause non-random mating). 2. Empirical data show that inbreeding depression is common and often produces strong effects on fitness, but is not universal.

These alleles are "identical by descent". The inbreeding … WebInbreeding also has the effect of increasing the variance among the individual demes of a larger population. As such, drift and inbreeding are closely related evolutionary forces. ...

When calculated across all the J:ARC variants and samples, the average level of inbreeding is −0.033 (−3.3%), which falls within the expectations for an outbred population (Yalcin et al. 2010). Though fewer samples were used to generate the J:DO dataset ...
WebUniversity of Washington WebJan 1, 2016 · Therefore, the general formula for the coefficient of inbreeding is F = Σ [ (0.5) n (1 + F A) where Σ is the sum of the paths through which an individual can derive identical alleles from his ancestors and n = the number of individuals in the paths. 1 + F A is the correction factor for the inbreeding coefficient of the common ancestor in the path.
