Inbreeding depression in Delphinium nelsonii. A. Overall fitness of progeny cohorts and the B. progeny lifespan were all lower when progeny were the result of crosses with pollen taken close to a receptor plant. [1] Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding (the breeding of related ...
Inbreeding avoidance, or the inbreeding avoidance hypothesis, is a concept in evolutionary biology that refers to the prevention of the deleterious effects of inbreeding. Animals only rarely exhibit inbreeding avoidance. [ 1 ]
Inbreeding in a population reduces fitness by causing deleterious recessive alleles to become more common in the population, and also by reducing adaptive potential. The so-called "50/500 rule", where a population needs 50 individuals to prevent inbreeding depression, and 500 individuals to guard against genetic drift at-large, is an oft-used ...
Genetic purging is the increased pressure of natural selection against deleterious alleles prompted by inbreeding. [1]Purging occurs because deleterious alleles tend to be recessive, which means that they only express all their harmful effects when they are present in the two copies of the individual (i.e., in homozygosis).
Below that, the inbreeding becomes a problem in the long term. Image credits: Lugbor #10. If you eat polar bear liver it will kill a human and if a polar bear eats your liver it will too.

Inbreeding depression is a trend in many plants and animals with small populations sizes and increases their risk of extinction. [ 10 ] [ 11 ] [ 12 ] Inbreeding depression is usually taken to mean any immediate harmful effect, on individuals or on the population, of a decrease in either type of genetic variation.
