From: Two genomic regions together cause dark abdominal pigmentation in Drosophila tenebrosa
Mean pigmentation scores of the F2 haplotypes derived from the two QTL with large effects on pigmentation. The letters denote the two alleles (S: D. suboccidentalis, T: D. tenebrosa), with S and T indicating hemizygous state of the X-chromosome in males, and SS, ST and TT indicating autosomes and the X-chromosome in females. A representative locus from each of the LGs was used, including y from the LG1 (the X-chromosome) and burs from LG3 (Muller Element C/E). Individuals are separated by backcross and by sex. The shading of the bars indicates an increasing number of D. tenebrosa alleles.
