Impact of missing data and minor allele frequency on the number of SNPs.

<p>(a) The number of SNPs (in ‘000’s) is plotted as a function of the maximal proportion (in %) of missing data tolerated (MaxMD) at three levels of minimal minor allele frequency (MinMAF). (b) Overall mean proportion of missing data (in %) for datasets obtained at different levels of MaxMD and MinMAF. (c) Distribution of SNPs called at different levels of missing data.
