QTL mapping of differences in LSJ2 and CX12311 reproductive rate and timing.

<p><b>a.</b> Schematic of egg-laying experiments performed on 94 recombinant inbred lines (RILs) generated between LSJ2 and CX12311. <b>b.</b> Histogram of the egg-laying rate measured from 94 RILs at five different time points. <b>c.</b> QTL mapping on data from B identified a major effect locus on the right arm of chromosome II at all five time points. Additional smaller effect QTL were identified for a subset of time points on chromosomes IV, V, and X. Stars identify QTL that reach genome-wide significance. <b>d.</b> Egg-laying rate of RILs partitioned by their genotype at the genetic variant with the peak LOD score (WBVar00601585) in the major effect QTL on the right arm of chromosome II. The effect of this variant was age dependent. Mean and s.e.m. plotted immediately to the right. Number in the upper right indicates percent of phenotypic variation explained by the QTL.
