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. In general, the higher the genetic variation or gene pool within a breeding population, the less likely i… WebJan 19, 2015 · In these experiments, Darwin documented the phenomenon of inbreeding depression because the offspring of self-fertilized plants were on average shorter, flowered later, weighed less, and produced fewer seeds than the progeny of cross-fertilized plants.

WebThe depression may be from very high to nil. Based on degree of depression, the plant species can be grouped into four broad categories. 1. High inbreeding depression Inbreeding leads to severe depression and exhibit lethal effects. After 3 or 4 generations of selfing it is hard to maintain lines. E.g. Lucerne, Carrot. 2.
