Web(i) It is the common form of outbreeding. (ii) It leads to heterozygosity. (iii) Allogamous species develop heterozygous balance and exhibit significant inbreeding depression on selfing. Q. 21. What are mechanisms which promote allogamy? Ans. The following mechanisms promote allogamy: (i) Dictiny: It refers to unisexual flowers. (ii) Dichogamy: 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 les…

WebThis is called inbreeding depression. 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.
