  • Heritability (h2) of the trait was either 0.4 or 0.7, the number of QTL (q) controlling the trait was either 20 or 50, and the effects of QTL followed a geometric series. The values in parentheses correspond to the percentage of parameter values observed using only CPS markers relative to complete marker information.
