Filtering to get the autosomes

Looking at hetereozygous versus homozygous on the sex chromosomes does not make sense, especially for males. So for these computations we will limit the datasets to the autosomes.

In the section Filter and Sort click on the Filter tool. Select the initial gd_snp dataset and type the condition as shown. If we had been using deep coverage SNPs here we could as filter by the overall score of the SNPs to get the higher quality SNPs as well. Since we are using low coverage SNPs we will filter by coverage later. Then click the Execute button.
