Evaluation of sire predicted transmitting abilities for evidence of X-chromosomal inheritance in north american sire families.

Abstract excerpt

This study tested for differences between genetic merits of sons and daughters of sires and for evidence of segregating quantitative trait loci on the X chromosomes of North American Holsteins. Son PTA adjusted for sire PTA was used as the dependent variable to test for biases and for genes that were passed from sire to daughter but not to son. The test of variability across sires of sons merely indicated an...
