WebInbreeding is the mating of (close) relatives or, mating of individuals with at least one common ancestor F ( Inbreeding Coefficient) = prob. of " identity by descent ": Expectation that two alleles in an individual are exact genetic copies of an allele in the common ancestor or, proportion of population with two alleles identical by descent 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 ...
