Schematic representation of the statistics computed for DT on the two F2 association studies (H5♂xW11♀ and H5♂xW37♀).

<p>Black bars show the difference (in percentage) between genotypic classes that developed faster and slower ((fast DT class – slow DT class)/slow DT class). The values next to the bars are the percentage of variation explained by each marker (the square of the Pearson correlation coefficient). For this calculation, we use the mean of each genotypic class as the expected value for that class. Significant associations are represented by *(0.05>P>0.01), **(0.01>P>0.001) and ***(p<0.001). n.a. – not applicable, the markers were not segregating in this F2 association study. Muller’s elements A – E are shown in A) to E), respectively.
