Prediction of fitness under different breeding designs in conservation programs

The expected change in fitness under inbreeding due to deleterious recessive alleles depends on the amount of load harbored by a population, that is, mutations concealed heterozygous state, and opposing effect genetic purging remove such load. This can be thus predicted if an estimate coefficient (the parameter quantifies purging) are available. These two parameters estimated pedigreed populations, as has been shown for populations random mating. A question arises whether these also other breeding systems well they allow accurate prediction corresponding fitness. In conservation programs, it is usually recommended preserve diversity equalizing contributions from parents progeny avoiding inbred matings. Regular have proposed strategies purge Using computer simulations, we first test method jointly initial subjected equalization parental contributions, circular mating, partial full-sib Then, using values variance family size, estimates coefficient, make simple predictions over generations compare them with simulation results. We discuss how help undertaking designs different scenarios.
