Woo! Biology class is paying off!

Inbreeding is good, Incestual Inbreeding is bad.

Inbreeding is the continued breeding of organisms with similar characteristics or traits. IE - Whitetail deer breed with Whitetail deer. This is good. This is what you want.

Incestual Inbreeding is the continued breeding of similar organisms from the same family. IE - A brother and sister breeding. This increases the possibility of a recessive allele being expressed rather than the normal dominant allele. This will cause retardation, deformities in the antler structure, etc... NOT good.

Just a little info on inbreeding, never thought I'd be able to use THAT stuff.
