Inbreeding and natural selection
WebThe issue with inbreeding is that it can reveal harmful recessive traits that would usually not be expressed (especially not lots of them together) in more outbred individuals. ... this actually sets up a very efficient form of natural selection that can totally remove harmful recessive alleles from a population's gene pool. This is called ... WebGenetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of …

The effectiveness of this purging process, however, may be influenced by the rate of inbreeding and the environment in which inbreeding occurs.

Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.
