Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck.

WebAug 19, 2024 · Inbreeding can be measured using one of two sets of approaches. The traditional approach involves generating a family tree — or pedigree — of all the individuals within a population, and estimating the relatedness between pairs of individuals by tracing back through the pedigree.

This can be overcome by crossing these animals with unrelated superior animals of the same breed having no common ancestors. This is called out-crossing. This restores the fertility and yield. Therefore, the best way to overcome inbreeding depression is by out-crossing. high vs low current ratio

"Webing depression. This is due in large part to the seminal but controversial work of Lande and Schemske (1985) and Schemske and Lande ( 1985). They postulated a direct link between levels of inbreeding depression and the evolution of self-fertilization, providing a rationale for measuring levels of inbreeding depression in plants.
