Pre-selection against a lethal recessive allele in breeding schemes with optimum-contribution selection or truncation selection

Table 3 Least-squares means for true genetic gain in generation \({t}\) = 2 according to pre-selection strategy and starting frequency of the lethal recessive allele at a 0.01 \(\Delta {\text{F}}_{{{\text{true}}4 - 10}}\) in a breeding scheme with genomic prediction

Pre-selection strategy	Starting frequency of the lethal recessive allele
Pre-selection strategy	0.05	0.10	0.15
No carriers culled	0.529^a	0.527^ab	0.529^a
Male carriers culled	0.523^ab	0.513^ab	0.500^b
Female carriers culled	0.516^ab	0.501^b	0.470^c
All carriers culled	0.507^ab	0.468^c	0.435^d

Means with the same superscripted letter are not significantly different from each other (p < 0 .05)
