Inbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination.
Genetic purging is the increased pressure of natural selection against deleterious alleles prompted by inbreeding. [1]Purging occurs because deleterious alleles tend to be recessive, which means that they only express all their harmful effects when they are present in the two copies of the individual (i.e., in homozygosis).
[3] In Shim-pua marriages , a girl would be adopted into a family as the future wife of a son, often an infant at that time. These marriages often failed, as would be expected according to the Westermarck hypothesis.
Inbreeding avoidance, or the inbreeding avoidance hypothesis, is a concept in evolutionary biology that refers to the prevention of the deleterious effects of inbreeding. Animals only rarely exhibit inbreeding avoidance. [ 1 ]
Though there are many traits about zebrafish that are worthwhile to study including their regeneration, there are relatively few inbred strains of zebrafish possibly because they experience greater effects from inbreeding depression than mice or Medaka fish, but it is unclear if the effects of inbreeding can be overcome so an isogenic strain ...

The effect of inbreeding in the resulting sub-populations could be studied by measuring the runs of homozygosity in different individuals. [4] In clinical laboratory testing, the detection of ROH in itself does not indicate a particular genetic disorder but indicates an increased risk of autosomal recessive inherited diseases. [5]
In an appearance on "The Pacman Jones Show," the Hall of Famer and Colorado coach made it clear what he thinks the future holds for his son.
