Cytological evidence of rescue of the autosomal pairing defect by expression of the UAS tef∷GFP transgene. A representative late prophase (S6) spermatocyte from a male bearing two copies of the UAS tef∷GFP transgene and the indicated GAL4 driver are shown. Each cell is oriented with the sex bivalent uppermost. Note the unpaired major autosomes in the cell lacking a Gal4 driver.
