Webb14 apr. 2024 · Genome-wide SNPs were filtered by PLINK software (version 1.9), and SNPs without close linkage were selected. Then, population structure analysis was performed according to K = 1 to K = 10 using ADMIXTURE (version 1.3.0) software, and 10 different seeds were selected for 10 replicate analyses. Webb17 jan. 2024 · To assess the distribution of mean heterozygosity across all samples, Plink was used (Purcell et al. 2007). The “–het” option in Plink was used to create heterozygous information for each sample which included the observed number of homozygous genotypes ”[O(Hom)]” and the number of nonmissing genotypes “[N(NM)]”.

WebbPLINK will generate a number of standard summary statistics that are useful for quality control (e.g. missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates). These can also be used as thresholds for subsequent analyses (described in the next section ). rain bricksWebb12 apr. 2024 · Background Breast cancer (BC) is the most common cancer and the second leading cause of cancer death in women; an estimated one in eight women in the USA will develop BC during her lifetime.
