Counts and frequency of alleles in called genotypes (AC, AF, AN)
This annotation outputs the following:
This set of annotations, relating to a heterozygous call(0/1) means there is 1 alternate allele in the genotype. The corresponding allele frequency is 0.5 because there is 1 alternate allele and 1 reference allele in the genotype. The total number of alleles in the genotype should be equivalent to the ploidy of the sample.
