Dear all, I am working on some variants and comparing them with 1000 genomes data. I would like to retrive the number of homozigote patients for the variant, the 1000g VCF file looks like a long list of 0|0 (or 1/2). I looked at their website (http://www.internationalgenome.org/category/genotypes/) but it is still unclear to me, how would a ALT HOM be specified? And an ALT HEM? What is the difference between 0|1 and 0|2 for example.

Thanks a lot in advance for any help!
