Table 4 Marker analysis for ovariole number in Drosophila melanogaster from analysis using intersection test, α = 0.025, two marker regression test α = 0.05; and interval mapping; only markers significant in either the two marker test or intersection test listed

From: Intersection tests for single marker QTL analysis can be more powerful than two marker QTL analysis
