  1. Model 1: the additive linear model; Model 2: the two-effect linear model; Model 3: the additive linear model including adjacent interactions between markers; Model 4: the two-effect linear model including adjacent interactions between markers; Model 5: the two-effect sex-dependent model treating sex as one additional group; Model 6: the additive linear model with 5 different kernels.
