Is a matrix (599 x 1279) with DArT genotypes; data are from pure lines and genotypes were coded as 0/1 denoting the absence/presence of the DArT. Markers with a minor allele frequency lower than 0.05 were removed, and missing genotypes were imputed with samples from the marginal distribution of marker genotypes, that is, \(x_{ij}=Bernoulli(\hat p_j)\), where \(\hat p_j\) is the estimated allele frequency computed from the non-missing genotypes. The number of DArT MMs after edition was 1279.
