TABLE 4.

Mean correlation between the simulated genotypic value of an individual and its predicted genotypic value for the epistatic and additive models ( and respectively) and the frequency with which the correlation was higher for the epistatic model than for the additive model [P(r_E > r_A)]

Setting			P(rE > rA)
1	0.499	0.473	0.78
2	0.508	0.479	0.86
3	0.509	0.510	0.50
4	0.516	0.515	0.58
9	0.516	0.524	0.36
10	0.536	0.540	0.34

Individuals for which the correlation was evaluated were in the fourth generation of the pedigree and had DNA marker data but no phenotypic record. Settings 9 and 10 here have N = 320 and N = 640, respectively, with Standard errors for correlations were less than 0.005.
