Why it matters in GWAS¶
Association models compare trait distributions across genotype classes; recessive tests contrast alternate homozygotes to all others, while standard additive tests treat dose 0, 1, 2 linearly. Homozygote calls are sensitive to QC (depth, allele balance) especially at rare variants.
Example usage¶
"Genotype QC and interpretation explicitly accounted for Homozygote status at candidate loci."
