Abstract

SANTOS, M.R et al. A rapid, non invasive and simple molecular method for sex determination in pygoscelis penguins. BAG, J. basic appl. genet. [online]. 2017, vol.28, n.2, pp.25-27. ISSN 1852-6233.

In Adélie penguins (Pygoscelis adeliae) and gentoo penguins (Pygoscelis papua), the conspicuous sexual dimorphism often makes it difficult to determine sex on the basis of external morphology. The information about sex is important in many ecology and conservation studies. In this paper we evaluated the use of an established primer pair (2550F/2718R) to identify sex in sexually monomorphic birds. In both penguin species, it resulted in two distinct CHD1Z and CHD1W PCR bands, allowing sex identification. This is a simple, rapid and cheap system for molecular sexing of gentoo and Adélie penguins.
