Hypothetical distribution of breeding values of F1 progeny of two matings (red and blue). The fractions of offspring with breeding values higher than the selection threshold (solid black line) are indicated in darker colors. The colored lines indicate the average breeding value of the selected fraction. a Using the same selection intensity for both matings as assumed in the calculation of ExpBVSelOff. b Using the same absolute truncation selection threshold for both matings as assumed in the calculation of ProbSelOff
