Figure 2From: A quantitative linkage score for an association study following a linkage analysisComparison of average χ2 values between random sampling and QLS sampling for various sample sizes. A. Two subpopulations: 20% of total variance is from an additive QTL in subpopulation 1, and no QTL effect exists in subpopulation 2. B. Four subpopulations with the QTL effect explaining 0%, 5%, 10%, and 20% of the total variance.Back to article page
