Figure 4From: Inference of haplotypic phase and missing genotypes in polyploid organisms and variable copy number genomic regionsIdentifying a switch error in the triploid case. In general we require at least N = 3 polymorphic sites to determine a phasing error, but because we can assume that the ordered haplotypes are correct up to and including marker m– 1, we can see immediately that there is a switch at position m between haplotypes 1 and 3.Back to article page
