Understanding Inbreeding Depression, Purging, and Genetic Rescue

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. WebMay 14, 2024 · Inbreeding often results in offspring that are weaker than their parents which can reduce the plant’s chance of survival. Many plants rely on animals to help them to breed. For example, bees carry pollen – containing the male sex cell – to other flowers which then fertilize the plant to produce seeds.
