Faculty inbreeding, that is, the practice of selecting former students of an institution as members of its faculty, has long been considered one of the fundamental problems of college and university . Introduction. Genomic selection increases selection response by reducing generation interval. Bulls were genotyped first due to cost. Now we have genotypes for many cows.
