Nucleotide alignment of a 685 bp Cht3 intron fragment in D.melanogaster and D.mauritiana . Cht3 intron sequence from the Drosophila melanogaster y; cn bw sp strain (accession AE002743). The Antonia LTR stretches from bp 1 – 264, where a black diamond (♦) indicates the end of LTR sequence. Strains representing the D. melanogaster, Africa (Dimonika) population and a strain representing the D. mauritiana, Mauritius population were sequenced. Sequences were aligned using MacVector (See Materials and Methods for details).
