摘要: Abstract Lee, C. 1999. Genetic antagonism between direct and maternal effects. J. Appl. Anim. Res., 15: 105–116. Negative genetic correlations effects for weaning weight were found from beef cattle data. There has been much debate over the biological existence of this antagonism. Recent research oil estimating correlation reviewed. To explain antagonism, inclusion direct-maternal covariance in analytical models was proposed, with a justification.
