Variance component estimatesa from 100 replicates with a marker homozygous individual in the base generation. The marker homozygote had a 50% chance of being QTL heterozygous.

The variance estimates are given as the mean of estimates from all simulations (All), and also as the mean of the estimates divided into two cases: marker homozygote simulated as QTL homozygous (Homozygotes) and marker homozygote simulated as QTL heterozygous (Heterozygotes)

a Standard deviations within parentheses.

b The allelic variance is estimated from model (1). The expected mean is half the proportion of the total variance explained by the QTL
