New inbreeding, according to Kalinowski, contributed to 71.8% of individual inbreeding, but ancestral ... WebTheir effective population size (Ne) was around 57.3, showing that the effect of selection, increasing the inbreeding, was counterbalanced by the management practices, intended to reduce the rate of inbreeding increase. The inbreeding of each individual was broken down into three components: old, intermediate and new inbreeding.
