  1. Percentage of genetic standard deviation and genic standard deviation retained by different selection criteria. Percentages are expressed relative to the first generation of the breeding program. Understand values as e.g., the genetic standard deviation in generation 5 was 79.4% as high as the genetic standard deviation in generation 0 when selecting based on ExpBVSelOff. Calculations follow the style of \(100\mathrm{\%}\left(\frac{\sqrt{{varG}_{criterion\_gen21}}}{\sqrt{{varG}_{crterion\_gen0}}}\right)\)
