Figure 3From: Forward-time simulation of realistic samples for genome-wide association studiesNegative of the base 10 logarithm of p -values of allele-based χ2 tests between 1000 cases and 1000 controls at 6000 markers (2000 each) on chromosomes 2, 5, and 10. Markers rs4491689 and rs6869003 are causal. Marker rs7720081 has low p-value because it is closely linked to marker rs6869003.Back to article page
