## Haplotype, LD, and Association Tests

Table of content Table of content What Are Haplotype and Linkage Disequilibrium (LD) Quantify LD Linkage Disequilibrium Coefficient ($D$): Standardized Linkage Disequilibrium Coefficient ($D’$) Correlation coefficient ($\gamma^2$) Now why do we care about LD and haplotype? LD is an indication of deviation from Hardy-Weinberg equilibrium. This is the first post of my QE prep series. I’ll be taking notes on my study for general knowledge section of my QE.
