  2. Mean square errors (MSEs) in cM2 of quantitative trait locus (QTL) location estimates and powers to detect the QTL obtained by the T2 and HAPim methods for various population and sample sizes. The single nucleotide polymorphism (SNP) marker spacing was 0.125 cM, t = 100, and the initial association was complete. The power was computed for a type I error of 0.05.
