How to get derived allele count for a list of SNPs

Question

[seta]

Hi all,

I was wondering how I can obtain the derived allele count for a list of SNP variants in human (hg 38)? I also have the corresponding vcf file for these variants. Also, please kindly let me know if I can use Fisher's test for comparing DAF (derived allele frequency) between populations? In this case, I also need the ancestral count for creating the contingency table, yes?

Any suggestions and comments would be highly appreciated.
