Fig 2. L. cuprina larvae with X-linked or autosomal fluorescent protein transgenes.

The lines carry a constitutively expressed DsRed-express2 marker gene. Larvae from an X-linked line (SLAM5) and an autosomal line (EF3C) are shown. In the X-linked line, the most brightly fluorescent larvae develop as females (F). The more weakly fluorescent larvae develop as males (M). In contrast, larvae from the EF3C line show a uniform level of fluorescence. Two representative larvae from this line are shown, the sex of the larvae is unknown.
