Table 5 Kinship and number of lost beneficial alleles relative to selection based on breeding values

	Average kinship			Number beneficial alleles lost
	Gen 1	Gen 5	Gen 21	Gen1	Gen 5	Gen 21
BV	0	0	0	0	0	0
ExpBVSelOff	− 4.4	− 5.3	− 1.4	− 2.5	− 6.8	− 3.5
ProbSelOff	− 4.5	− 6.6	− 2.3	− 2.7	− 7.7	− 4.9
Index5	− 4.7	− 4.1	− 2.2	− 1.2	− 5.0	− 4.0
ExpBVSelGrOff	− 7.3	− 7.0	− 0.3	0.3	− 12.4	− 4.0
ProbSelGrOff	− 8.4	− 8.2	− 2.1	− 1.7	− 9.6	− 5.6

Percentage difference in kinship level and number of lost beneficial alleles. Negative values need to be understood as benefit, i.e., less kinship or less lost beneficial alleles. Values have to be interpreted as e.g., ExpBVSelOff based selection lost 6.8% less beneficial alleles than breeding value based selection after 5 generations. Calculations follow the style of \(100\%\left(\frac{{\overline{kinship} }_{criterion\_gen21}-{\overline{kinship} }_{gen0}}{{\overline{kinship} }_{BV\_gen21}-{\overline{kinship} }_{gen0}}\right)-100\%\)
