Abstract

Sex determination refers to the developmental programme that commits the embryo to either the male or the female pathway. There are a plethora of mechanisms via which gender is decided. These mechanisms can be classified into three main categories depending on the origin of the primary, genetic, sex-determination signal, which can be zygotic, maternal or environmental. In the dipteran Sciara, the zygotic signal is a consequence of the maternal signal, and this in turn can be a consequence of the environmental signal. This makes Sciara a unique experimental model for studying the evolutionary relationships between the three primary signals triggering sexual development.
