Webvcffilter works with simple conditional statements, so this filters out loci with an allele balance below 0.25 and above 0.75. However, it does include those that are close to zero. The last condition is to catch loci that are fixed variants (all individuals are homozygous for one of the two variants). Web8.1.4 Adherence to Hardy-Weinberg distribution. The quality control based on Hardy-Weinberg (H-W) distribution is a bit trickier to explain. You might know the definition of the Hardy-Weinberg rule from population genetics which states that genetic variation (thus allele and genotype frequencies) in a population will remain constant unless certain disturbing … WebMar 10, 2024 · 2.
