Indy gene variation in natural populations confers fitness advantage and life span extension through transposon insertion
Figure 3. Hoppel insertion in Indy shows evidence for positive selection at the sequence level. The DNA sequence polymorphisms 1000bp upstream and downstream from the Hoppel insertion site are shown in red blocks. The standard reference D. melanogaster genome sequence is at the top with nucleotide position for each polymorphic site referenced to the Hoppel insertion site as position 0. The upper half of the figure are strains containing the Hoppel insertion (Hoppel +/+) and the bottom half lines are strains that do not have the Hoppel insertion (Hoppel −/−) (
