Inbreeding articles

Inbreeding can be just as much of a problem with Apistos as any other
animal. Excessive inbreeding can weaken the line and cause deformities,
infertility, and just plain weaker/shorter-lived fish. Most breeders will
periodically cross in new genetic material, either from someone else's line
or from wild stock. This helps to prevent excessive buildups of deleterious
mutations and can create opportunities for new phenotypes to pop up.


Speaking of that, I just posted two articles on inbreeding on my website. Both were written for Flare, the betta journal, but are applicable to apistos too. The first was written by me and tries to make the point that inbreeding has some benefits in that it can remove lethal recessives from a line (However, I don't advocate this for apistos or any other fish that we're trying to keep as close as possible to "wild".) . The second article (much nicer than mine!) and was written by Dr. Leo Buss, a professor at Yale. He explains the mechanisms by which inbreeding can cause problems. It's a really nice article.
