  • Expected RE of MAS compared with phenotypic selection for different biological parameters (number of QTLs, QTL effects distribution, and heritability h2 of the trait) and experimental parameters (m2 and the corresponding the rate of recombination between marker and QTL, r, population size N, and type I level risk, α). The total number of markers is 30.

  • a r indicates the corresponding rate of recombination between marker and QTL.
