We, therefore, propose that zebrafish sex determination is polygenic. The nine superclones examined in this study had been defined in earlier work on the basis of multi-locus microsatellite genotyping over 7—9 loci that included both autosomal and X-linked loci A.

They are composed of DNA and proteins and are located within the nucleus of our cells. They are called the autosomes. This method has been successfully deployed in many plant 18 and animal 21 species. Wildlife Research 39—

The F 3 mean sex ratios of the two families were The fact that sex ratios of different batches of offspring from the same breeding pair were very similar suggests that sex in zebrafish is heritable, whereas wide-ranging sex ratios across the families point towards a complex genetic trait.
