  • a Variance components were estimated using the VAR-COMP procedure of SAS and then set equal to their expectations under a strictly additive model of quantitative variation.

  • b For all genetic backgrounds, the effect associated with sex*-marker was very small or zero, so it was set equal to zero for the calculations here.
