Testing and Improving the Accuracy of Discriminant Function Tests: A Comparison between Morphometric and Molecular Sexing in Macaroni Penguins

Abstract:

Dimorphism in various morphological traits is widely used to sex birds. However, when a threshold is set and there is overlap in the distribution of traits between sexes, there will be an error rate. Macaroni Penguins show limited sexual dimorphism in size, with the distributions of most phenotypic traits overlapping between sexes, making using morphological characters for sexing difficult, although bill depth is used in one discrimination test Two existing DNA-based PCR tests that use differ...
