The Pricopian «gene theory of sexuality» is just a hypothesis, but good enough to explain the sex determination in fish.

Abstract
The present paper summarizes the Pricopian theory of sexuality, discussed in the context of fishes’ sex determination. On a logical approach and considering the most recent genetic evidences reported from studies on bacteria, invertebrates, fish, frogs, reptiles, birds, mammals and even humans, one may allready abandon the chromosomal concept of the sex determination (such as the dosage of Z chromosomes). The sex-determining locus is not a true locus, but an agglomeration of loci very seldom separated by genetic recombination. Moreover, the W chromosome in ZZ-ZW systems and the Y in XXXY systems are not empty at all, but still carry information.
