Random regression modelling of genetic covariance when data are available for litters: an application in mice.

Abstract excerpt

A recently published model for litter weight in multiparous species defines genetic dam and sire effects as linear random regression slopes on litter size. Building on the interpretation of these effects in terms of maternal and direct breeding values for birth weight, we show how to convert estimates of genetic covariance parameters from that model into direct and maternal genetic (co-)variances for birth...
