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 ... WebThis trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait! There are 4 mechanisms of evolution (how evolution happens): natural selection. mutation. genetic drift, and.

What is selective breeding? – YourGenome
WebNov 12, 2012 · There was strong directional selection favoring large eggs for both inbred and outbred beetles; offspring from smaller eggs had lower survivorship on a resistant host. Inbreeding treatment had no effect on the magnitude of selection on egg size; all selection coefficients were between ~0.078 and 0.096, regardless of treatment. WebIntroduction. 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. All of our domesticated species, including crop plants, livestock, and ...
