Relationship between sire x year interactions and direct-maternal genetic correlation for weaning weight of Simmental cattle.

Journal of animal science - 1 Jan 1997

Lee C, Pollak E J

Abstract excerpt

The interrelation of sire x year interactions (SY) and direct-maternal genetic correlation (rdm) for weaning weight was examined for bias in estimating rdm. Weaning weight records were simulated using models containing SY (D1), rdm (D2), or both (D3). When D1 data were analyzed ignoring SY, a nonzero rdm was observed, and direct and maternal genetic variance estimates were inflated. Analysis of D2 data ignoring...
