Additional Information
Statement
Reference

In the head and thorax, Cyp4d21

(Fujii et al., 2008)

is mainly expressed in cells associated with the long mechanosensory bristles of males. It is also observed in the labellum and maxillary palps, where expression is much stronger in males than females.
