An explanation that fits these observations is that genes affecting embryonic survival would be deleterious recessives and rare in the initial population, and hence selection for reduced litter size would increase their frequency and thereby yield a greater response than would reducing the frequency further in the high line. Ultimately, limits to selection will be reached at which all favorable alleles are fixed and no genetic variation remains.
