inbreeding

Mating of the closely related. Inbreeding tends to promote similarities and to deny access to new genes. It increases the chances of offspring being HOMOZYGOUS for RECESSIVE genes and thus manifesting the effect but, in itself, has no inherent tendency to produce bad characteristics. Its reputation so to do arises from the observation of the undesirable effects of inbreeding in the genetically disfavoured.

inbreeding

any mating between relatives, which can lead to a general lowering of viability due to accumulation of deleterious genes, often in the HOMOZYGOUS state, passed on through both parents from a common ancestor. Compare OUTBREEDING.
