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 |

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).
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.
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.
