How does inbreeding lower fitness

WebThe first point is that individuals that inbreed typically produce offspring that have lower fitness than individuals that outbreed (e.g., they have offspring with a lower probability of survival), a phenomenon called ‘‘inbreeding depression’’. WebThe offspring resulting from inbreeding tend to have health problems and lower reproductive success. This is known as inbreeding depression — and was seen in the Florida panthers in the form of poor sperm quality, low fecundity, undescended testes, kinked tails, and heart problems.

WebJun 2, 2024 · However, inbreeding can result in a higher chance of expressing deleterious recessive mutations as shown in figure 01. Hence, there is a high probability in offspring of carrying deleterious recessive traits due to the increased homozygosity by inbreeding.

WebInbreeding may or may not lead to inbreeding depression, which is a reduction in the fitness in the offspring produced by inbred matings.
