Linkage disequilibrium and haplotype
Nettet15. jul. 2011 · Researchers have compared the power of single-SNP and haplotype-based association analysis in different genetic scenarios. The benefit of including haplotype-tagging SNPs, especially those based on a cluster of 2–3 SNP markers, has been well recognized after the discovery of “block-like” linkage disequilibrium (LD) … Nettet15. des. 2005 · A new method for linkage disequilibrium mapping: haplotype pattern mining (HPM), based on discovery of recurrent patterns, which is model-free, in the sense that it does not require (and is unable to utilize) any assumptions about the inheritance model of the disease.

A key impact of demographic bottlenecks is an increase in linkage disequilibrium (LD). ... This underestimation of recombination events due to CO of identical haplotypes would be expected to be higher in genomes from more inbred …
In the absence of evolutionary forces other than random mating, Mendelian segregation, random chromosomal assortment, and chromosomal crossover (i.e. in the absence of natural selection, inbreeding, and genetic drift), the linkage disequilibrium measure converges to zero along the time axis at a rate depending on the magnitude of the recombination rate between the two loci. Using the notation above, , we can demonstrate this convergence to zero as follows. In the next … NettetAbstract.
