A Simulation Study of Truncation Selection for a Quantitative Trait Opposed by Natural Selection

Abstract: A quantitative character controlled at one locus with two alleles was submitted to artificial (mass) selection and to three modes of opposing natural selection (directional selection, overdominance and underdominance) in a large random-mating population. The selection response and the limits of the selective process were studied by deterministic simulation. The lifetime of the process was generally between 20 and 100 generations and did not appear to depend on the mode of natural selection. However, depending … Show more

“…The increasing opposition of natural selection often causes a cessation of response in artificial selection experiments. In spite of genetic variation for the selected trait, a limit to selection is reached which can be characterised by an unstable equilibrium between these two forces (A1-Murrani 1974; Verghese 1974;Minvielle 1980;Nicholas and Robertson 1980).…”
