The heterozygosity rate of an individual is the proportion of heterozygous genotypes. …
WebbMy sample is females only. --het gives an observed heterozygosity of 40% for my example individual, while if I calculate the average o (het) of autosomal snips of the same individual from a .hwe file, o (het) is 30%. For expected heterozygosity the numbers are 36% vs 16%. Webb27 mars 2024 · We estimated heterozygosity of autosomal regions from each of the 3 high coverage type D diploid genomes and made direct comparison to the globally sampled dataset of Foote et al. (2024). Under the infinite sites model (Kimura 1969), individual heterozygosity is a good, unbiased estimator of the population mutation rate, theta (θ; …
Webb17 jan. 2024 · The mean heterozygosity for the J:ARC samples is 0.25, while in J:DO, it is 0.39. To compare the variant level heterozygosity between the two populations, we identified the variants that are common between J:ARC and J:DO, and then for each variant, we determined the number of samples with heterozygous genotypes ( Fig. 2b ).
