Find polymorphic genotypes from merged vcf file

[bioinfoanalyst]

Hi Github community,

I want to filter out homozygous, heterozygous and missing genotypes from multi-sample single vcf file and need to keep only polymorphic alleles. Kindly suggest which tool or strategy should i employ to get only polymorphic genotypes.

Thanks
