Abbreviation: SNP, single nucleotide polymorphism.

Data were simulated according to model (1). : residual variance for trait : residual correlation between trait 1 and 2, ratio of the genetic variance to the residual variance for trait : genetic correlation between trait 1 and 2, ratio of the quantitative trait loci variance to the residual variance for trait k.
