Figure 4From: LTR retrotransposons and the evolution of dosage compensation in DrosophilaImmunostaining of Drosophila polytene chromosomes with MOF -antibody. Shown are preparations from strains representing two Drosophila species- (a) D. melanogaster and (b) D. simulans. Reduced binding of MOF to D. simulans autosomes is consistent with the reduced number of LTR retrotransposons present in this species.Back to article page
