Figure 1: Linkage disequilibrium of 20 SNPs in the 1p13 2 region shows a well-de ned hap-lotype with strong correlations from SNPs 13 to 18 and weak and di use correlations from SNPs 1 to 12 3 2 Large well-de ned haplotype in the 8p23 1 region The chromosome 8 region 8p23 1 is the largest inversion haplotype in humans and includes

Human eye colour and HERC2 OCA2 and MATP

Linkage Disequilibrium •Non-random association of alleles at different loci within a population •Alleles are found together more or less often than you would expect by chance if all alleles randomly and independently segregated during meiosis •Scores range from 0 (not in LD) to 1 (in complete LD) •Two ways to measure LD: D’ and r2

Introduction to Linkage Disequilibrium - Brown University

Linkage Disequilibrium: correlation between two loci p 11 = probability of seeing the A 1B 1 haplotype p 12 = probability of seeing the A 1B 2 haplotype p 21 = probability of seeing the A 2B 1 haplotype p 22 = probability of seeing the A 2B 2 haplotype The sites are in Linkage Equilibrium if p 11 = p 1q 1 p 12 = p 1q 2 etc Sorin Istrail

SNP Selection for a Linkage Disequilibrium Marker Set Selecting SNPs within gene regions at an average density of one per 10 kb makes our map resemble a gene-focused picket fence Currently the gene list we use includes about 27000 gene regions derived by Celera Genomics The candidate SNPs are selected from the

Linkage Disequilibrium Example Consider two SNPs in the coding region of glycoprotein A and glycoprotein B that change the amino acid sequence Both of the proteins are on chromosome 4 and are found on the outside of red blood cells SNP for Protein A has two alleles: A and G SNP for Protein B has two alleles: T and C Protein SNP Allele Amino Acids

Linkage disequilibrium (LD) mapping presents a powerful alternative to linkage analysis for the map-ping and detection of genes with a modest effect on risk 3–5 LD is a complex phenomenon and it

Which HERC2 SNPs are in strong linkage disequilibrium?

The highest predictive value of typing either the HERC2 SNPs rs1129038 and/or rs12913832 that are in strong linkage disequilibrium was observed when eye colour was divided into two groups, (1) blue, grey and green (light) and (2) brown and hazel (dark).

What is linkage disequilibrium?

The nonrandom association between the CD4 STRP alleles and the Alu(-) allele is referred to as linkage disequilibrium Table 1. Unweighted mean CD4 STRP-Alu frequency estimates and standard errors (in parentheses) for seven regions of the world.

Can linkage disequilibrium mapping be used in natural plant populations?

The possibility of using linkage disequilibrium mapping in natural plant populations was assessed. In studying linkage disequilibrium among 137 mapped AFLP markers in four populations of sea beet (Beta vulgaris ssp. maritima (L.) Arcang.) it was shown that tightly linked loci could be detected by screening for associations.

Is linkage disequilibrium delayed in self-pollinated crops?

? The decay of linkage disequilibrium is delayed in selfing populations ? Important for association mapping in self-pollinated crops Mutation ? Effect is generally small absent recombination and gene flow
