Does Inbreeding Correct Itself

According to theory, inbreeding would reduce fitness due to increased homozygosity and expression of recessive deleterious alleles. However, after some generations of continuous inbreeding these deleterious alleles would no longer remain in the population and the individuals would experience an increase in fitness (Fowler and Whitlock, 1999). This loss of inbreeding depression [reduced fitness due to inbreeding] due to continuous inbreeding is called purging, and can be seen as a reduction of the genetic load [the existence of recessive deleterious alleles
in a population] of the population (Barret and Charlesworth, 1991). This could mean that individuals in a regularly outbreeding population would suffer more from an instance of inbreeding than individuals in a regularly inbreeding population (Bengtsson, 1978; Charlesworth and Charlesworth, 1987; Mitton, 1993).
One example of this comes from dwarf mongoose in Serengeti, who experience very little inbreeding depression even though incest is very common (Keane et al., 1996).

I'll admit I ripped this post off of this forum. http://www.biodiversityforum.com/viewtopic.php?t=2944&sid=89a61099ec1a9224772fdc7b7c15d2fa

In a purely physical sense, yes, it does, but it's not that simple.

Survivability of a population isn't simply due to having or lacking 'mutations' and how fast you can run or whatever.

It is often due to diversity in the immune system, having valuable mutations. Many mutations we think are bad, have benefits in fighting certain disease. Sickle sell anemia for example, it sucks hard but when everyone has malaria (or something like that) then they live longer.

Of course, with the development of science and medicine, having diseases to fight diseases probably isn't needed (or is much less important) so the taboo could easily be harmlessly discarded I think.
