title: The hidden value of missing genotypes.
abstract: Robotic systems allow vast genetic data sets to be generated automatically with little manual input, raising questions about accuracy. To test whether errors occur randomly, I used the frequencies of missing genotypes in a large human data set to construct a population tree. Remarkably, the gaps appear to carry as strong a phylogenetic signal as the actual data themselves.
