Linkage disequilibrium (LD), which refers to nonrandom association of alleles(等位基因的非随机性组合） at different loci(位点；基因座)。 LD指等位基因在不同位点（或基因座）的的非随机性组合。Block:阻滞 linkage diseqquilibrium block：等位基因在不同基因座的非随机性组合障碍 因为对这方面不...

Each SNP represents a difference in a single DNA building block, called a nucleotide. 狭义上讲是标记:biological markers,因为SNP是单碱基的,所以SNP又是一个位点,标记了染色体上的一个位置。大部分人的基因组,99%都是一模一样的,还有些SNP的位点,就是一些可变的位点,在人群中有差异。这些差异/标记可以用...
The development of linkage disequilibrium (LD) maps and the characterization of haplotype block structure at the population level are useful parameters for guiding genome wide association (GWA) studies, and for understanding the nature of non-linear association between phenotypes and genes. The elucidati...
Above, it was noted that linkage disequilibrium may contribute to an apparent association; this has sometimes been referred to as ‘hitch-hiking’. This is said to occur when specific alleles at two different loci are found together more than expected. This may result fromnatural selection, or ...
Existing SNP-heritability estimators that leverage summary statistics from genome-wide association studies (GWAS) are much less efficient (i.e., have larger standard errors) than the restricted maximum likelihood (REML) estimators which require access to
b Our method compares reads from two datasets across a genome-wide set of linkage disequilibrium (LD) blocks (haplotype map). The single-nucleotide polymorphisms (SNPs) in each block are highly correlated with each other and have low correlation with SNPs in other blocks. Reads overlapping any ...
