Vääetisained

Vääetisained, also known as inbreeding depressants or inferior alleles, refer to the genetic properties of an organism that become less pronounced or even invisible when they occur in individuals with similar genotypes.

The term was introduced by Estonian geneticist and patriot August Weeping as part of an article on the ethnic genome in 1928. This concept has since been widely discussed in the context of genetics, ecology, evolutionary biology and breeder improvement issues.

According to August Weeping, the vääetisained can manifest themselves in several different forms, including unbalanced sex ratio, abnormally early death, affectation of the number of generations, along with deleterious decreases in proportions.

It's widely understood that natural selection can remove adverse alleles, resulting in populations that are more favorable in health, physique and potentially even increased strength and endurance over the long term.

Furthermore, the abundance of vääetisained in a domestic population would have a negative effect on its fitness, although, genetic degradation may be irreversible under wide-definition accruals.

The study of vääetisained is also used in conservation biology, such as understanding how genetic diversity contributes to maintaining resistant and viable populations.

Research has shown that populations that have undergone intense selective pressure or artificial selection may carry significant genetic loads, explained by an abundance of vääetisained.

Some researchers suggest that studying vääetisained is also useful in artificial selection, as it can hinder down natural consequence of undesirable traits in high degree genotypes, promoting recessive alleles that are possibly beneficial but are based around alleles which will combine in disadvantageous ways.
