摘要

新热带cormorant（Phalacrocorax brasilianus）是一种单形态物种，广泛分布于美洲大陆。我们使用了一种快速有效的分子技术，以染色体解旋酶DNA结合基因为中心，根据内含子的大小来区分男性和女性性染色体。雄性呈现Z染色体，具有664个碱基对的单条带，雌性呈现相同的带加上与W染色体相对应的最短的带，具有459个碱基配对。

Sex determination of Neotropic cormorant (Phalacrocorax brasilianus) by molecular sexing

Neotropic cormorant (Phalacrocorax brasilianus) is a monomorphic species widely distributed along the American Continent. We used a rapid and efficient molecular technique centred on the chromo-helicase-DNA-binding gene in order to differentiate male and female sex chromosomes based on the size of introns. Males presented a Z chromosome with a single band of 664 base pairs, and females presented the same band plus a shortest one corresponding to the W chromosome with 459 base pairs.

期刊介绍： Avian Biology Research provides a forum for the publication of research in every field of ornithology. It covers all aspects of pure and applied ornithology for wild or captive species as well as research that does not readily fit within the publication objectives of other ornithological journals. By considering a wide range of research fields for publication, Avian Biology Research provides a forum for people working in every field of ornithology.
