3.10.1. Genotype Zygosity¶
This algorithm examines the genotypes for each sample and identifies them as one of the following:
Reference: Both alleles match the reference allele
Heterozygous: Two different alleles
Homozygous Variant: Both alleles are the same but are different than the reference allele.
Hemizygous: The single allele present is different than the reference allele.
Requires a genotype (GT) sample level field.
Creates a zygosity field for each sample.
