For each of the 100 drones, N variants were randomly pruned in 1 Mb windows, with N ranging from 12.5 K to 750 K SNPs. WitrynaImputing genotypes at ungenotyped markers using a reference panel Table 1b shows an example of markers that are not geno- typed in the sample but that are genotyped in a reference panel (SNPs 2 and 5). The reference panel is essential if the genotypes at the ungenotyped markers are to be inferred in the sample.
