All five models were selected becausethey exhibit interaction effects in the absence of any main effectswhen allele frequencies are equal and genotypes are generated usingthe Hardy-Weinberg equation. In addition, we selected models withina range of heritability values. As mentioned previously, ...
The Hardy-Weinberg equilibrium (HWE) of genotypes describes the random combination of male and female gametes in a randomly mating population. In HLA studies deviation from HWE has been used to infer typing inaccuracies, possible selection and population stratification. Here we show that in large ...
The GEBVs accuracy was calculated based on prediction error variance (PEV) and the genetic variance for each trait ([Math Processing Error]\unicodex03C3a2) using the following equation [16]: [Math Processing Error]Acc=1−PEV/\unicodex03C3a2. The GEBV was estimated using the following ...
When the Hardy–Weinberg equilibrium in the population is not severely violated, MCPDTI still controls the type I error rates well under the null hypothesis of no association from our simulation study. Further, power comparison demonstrates that PDTI and MCPDTI are more powerful than PDT and TD...
In a nutshell, HEELS uses variant-level statistics, including marginal association statistics and the LD matrix, to estimate SNP-heritability by iteratively solving the REML score equation17. Because the score equations solved by HEELS are identical to those solved by GREML1, HEELS yields heritability...
The samples were genotyped using a 50 K SNP Illumina BeadChip [18] and filtered using departure from Hardy- Weinberg Equilibrium (HWE, p-value 10− 6), minor al- lele frequency (MAF < 0.01), and a genotyping call-rate for SNPs and samples of < 0.90. After quality control 29, 587 ...
In the quality control for genomic data, single nucleotide polymorphisms with minor allele frequency, call rate, and P-value for Hardy–Weinberg equilibrium test less than 0.02; 0.95 and 0.15, respectively, were excluded. Only single nucleotide polymorphisms in autosome chromosomes and with known posi...
if the Hardy-Weinberg equilibriump-value was <1 × 10–6, and/or if the call rate was <0.95. The genotype data was then aligned with the 1000 Genomes reference panel using the HRC and 1000 Genomes checking tool, testing and filtering for SNPs with allele frequency differences larger ...
METHODS When an offspring descends from parents with different ancestries, a departure from Hardy–Weinberg equilibrium (HWE) is induced in all autosomal loci that one might genotype in the offspring. To take an extreme case, if the parents are 100% divergent, then parent 1 will be homozygous...
