This inbreeding may lower the population's ability to survive and … WebEstimates of inbreeding depression based on the loss in fecundity expected from the smaller size of inbred females ranged from 0.10 to 0.39 (Table I ), depending on the equation used to predict fecundity (clutch size) from female size.

Inbreeding depression is often the result of a population bottleneck. In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression, though inbreeding and outbreeding depression can simultaneously occur.
