Fig. 2From: A unique cluster of roo insertions in the promoter region of a stress response gene in Drosophila melanogasterThe majority of the insertions in the CG18446 promoter region are present at very low allelic frequencies. Allelic frequencies of the 20 roo solo-LTRs insertions in populations from Europe, North America, and Africa. The number of strains analyzed in each population is given in parenthesis and the pie chart size is proportional to this number. Blue, yellow, and red lines represent populations with cold, temperate, and arid climates, respectivelyBack to article page
