Inbreeding effective size
WebJun 29, 2016 · The concept of effective size is key to conservation genetic practices, as it summarises the past history of the population regarding inbreeding and genetic drift and … 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.
