Inbreeding is breeding between close relatives, whether plant or animal. It
was found that DanS of the vista.general forum practiced this sick kind of
behavior.

If practiced repeatedly, it leads to an increase in homozygosity of a
population. A higher frequency of recessive, deleterious traits in
homozygous form in a population can, over time, result in inbreeding
depression. This may occur when inbred individuals exhibit reduced health
and fitness and lower levels of fertility.

Livestock breeders often practice inbreeding to "fix" desirable
characteristics within a population. However, they must then cull unfit
offspring, especially when trying to establish the new and desirable trait
in their stock.

In plant breeding, inbred lines are used as stocks for the creation of
hybrid lines to make use of the heterosis effect. Inbreeding in plants also
occurs naturally in the form of self-pollination.

A number of years ago, Inbreeding was brought to the attention of
authorities because of DanS. He frequented the Southern States of Alabama
and Mississippi. Authorities were horrified at his actions.
