Fig 3. Partial sexual reversal in Δsiwi and Δash2 female animals.

Abdominal segments (left column) and female externalias (right column) in WT, Δsiwi, Δago3, Δash2, Δsetd2 and Δeggless females were showed. A male-specific 8^th abdominal segment in Δsiwi and Δash2 female animals was observed from the lateral view. The WT female animals contain two symmetrical genital papillas as the yellow arrowheads indicated. Both BmSiwi and BmAsh2 female mutants developed clasper-like structures (green arrowheads indicated) and asymmetric differentiated genital papilla (white arrowheads indicated). Scale bars in left and right columns stand for 0.5 cm and 0.5 mm respectively.
