Extract

Dam genotype affects the phenotype of progeny through a sample of direct additive genes for growth and maternal effects on growth (Meyer, 1992). In this study (co)variance components due to direct and maternal effects were estimated for 50 day weight of Welsh Mountain lambs reared in a hill environment. The data set was based on ewes in an embryo transfer trial providing an opportunity to examine maternal effects based on larger numbers than usual of progeny per genetic dam.
