Cumulative response to selection plotted against the used genetic variance at generation 40 for a grid of 36 sub-scenarios with nine recombination rates and four selection intensities for a trait based on 10,000 quantitative trait variants (QTV). Recombination rates are connected with a solid line. Red color defines the typical chromosome length (CL) of 1 Morgan (CL1M_T), and the scale of blue ranges from low recombination rate (light blue, CL0.1M0) to high recombination rate (dark blue, CL20M). The different proportions of males selected as sires at each recombination rate are connected by a dotted line, and range from 10 % (square symbol) to 1.2 % (diamond symbol). The grey area highlights a set of sub-scenarios that used similar amounts of genetic variance, but produced different levels of response to selection. This set of sub-scenarios was chosen and explored in Fig. 5
