Introduction:
Cell and tissue-specific regulation of expression of genes is important for the proper development of an organism. Some proteins that have been implicated in this regulation are PcG protein complexes and TrxG (Trithorax group) protein complexes.

Homozygous (m-m-) males, however, can still produce viable sperm.
