Abstract

It is known that in the silkworm (Bombyx mori), males have two Z sex chromosomes whereas females have Z and W and the W chromosome has a dominant role in female determination; here a single female-specific W-chromosome-derived PIWI-interacting RNA is shown to be the feminizing factor in B. mori.
