Evolution of genetic variation across generations. Genetic standard deviation (gSD) after four generations of random mating without selection (deemed unimpacted by the Bulmer effect) relative to gSD in generation 0 (a) and relative to gSD from breeding value selection schemes in the same generation (b). Genic SD relative to that in generation 0 (c) and to that from selection schemes based on breeding values (d). Values are the ratios obtained from the calculation of (\(\frac{\sqrt{{varG}_{criterion\_gen21}}}{\sqrt{{varG}_{BV\_gen21}}}\))
