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

Table 7 Least-squares means for rate of true inbreeding from generations \({t}\) = 1 to 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	0.0196^a	0.0193^ab	0.0192^abc
Male carriers culled	0.0194^ab	0.0187^abc	0.0186^abc
Female carriers culled	0.0188^abc	0.0184^bc	0.0172^d
All carriers culled	0.0189^abc	0.0183^c	0.0185^bc

Means with the same superscripted letter are not significantly different from each other (p < 0.05)
