Table 1.

Scenarios with different number of QTL and distribution of QTL variance.

Scenario	Number of QTL	Distribution of QTL variance
1	low	unequal
2	intermediate	unequal
3	high	unequal
4	low	equal
5	intermediate	equal
6	high	equal

Scenarios were numbered from 1 to 6, according to the number of QTL contributing 90% of the genetic variance.
