El descubrimiento en aves del gen CHD-W, exclusivo para hembras y CHD-Z, presente en ambos sexos (hembras, ZW; machos, ZZ), ha permitido desarrollar un metodo universal de su sexaje, que consiste en localizar los dos genes conservados CHD (chromo-helicase-DNA-binding), ubicados en los cromosomas sexuales, exceptuando Ratitae, donde se plantea que estos no sufrieron ningun tipo de mutacion previa a la divergencia aviar, y por ello son indistinguibles y morfologicamente similares a los cromosomas autosomicos (GRIFFITHS et al., 1998; FRIDOLFSSON & ELLEGREN, 1999).
