Current theories of sex-determination in birds include the presence of an ovary-determining gene on the female-specific W-chromosome, and a dosage mechanism based on the number of Z-chromosomes females have one Z and one W sex chromosome while males have two Z sex chromosomes Here we have examined three lateral gynandromorph chickens a rare, naturally occurring phenomenon in which one side of the animal appears male and the other female to investigate the sex-determining mechanism in birds.

The lability of sex-determination systems in fish makes some species sensitive to environmental pollutants capable of mimicking or disrupting sex hormone actions. Such observations provide important insight into potential impacts from endocrine disruptors, and can provide useful monitoring tools for impacts on aquatic environments.
