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

Table 9 Least-squares means for the proportion of replicates where the frequency of the lethal recessive allele increased 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	0.378^a	0.365^a	0.315^b
Male carriers culled	0.065^de	0.027^def	0.003^f
Female carriers culled	0.132^c	0.073^d	0.020^ef
All carriers culled	0^f	0^f	0^f

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