Inbreeding Depression And Its Evolutionary Consequences

WebDec 15, 2024 · Outbreeding depression has been documented most commonly in plants because their relatively low dispersal rates, which are often combined with local adaptation to particular environmental conditions, mean that plants can show genetic differentiation over both small and large spatial scales. WebInbreeding 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.
