A low-marker density implementation of genomic selection in aquaculture using within-family genomic breeding values

Table 6 Genetic gain (σ _g ) of SIB ¹ for varying numbers of test-individuals with phenotypes and/or genotypes for within-family and conventional selection

Number of sibs with phenotype	W-FAM²– all sibs genotyped	W-FAM²– half of sibs genotyped	CONV
10	0.57 (0.012)	0.57 (0.011)	0.52 (0.011)
20	0.68 (0.010)	0.67 (0.011)	0.60 (0.011)

¹ A trait measured on full-sibs of the selection candidates
² W-FAM = genomic selection with marker effects estimated within full-sib families and combined with conventional BLUP family breeding values. 10% of the candidates were pre-selected, and pre-selected candidates, and all or half of their test-individuals, were genotyped for 12 markers per Morgan.
