... using the current sib -breeding design of family-based aquaculture breeding schemes, which was not optimised in any way for genomic selection, show that genomic selection yields high genetic gain, ... dramatically reduced by 81% for the genomic selection schemes compared to the traditional BLUP breeding schemes, although in practical breeding schemes, a way of reducing rates of inbreeding would probably ... using both between- and within-family genetic variances The aim of this paper was to investigate genetic gains, inbreeding and the accuracy of selection in a general genomic selection scheme for...
