This study tested 50 birds species from 11 orders and successfully sexing 47 of the species. However, two of them resolved two bands in acrylimide gel. Secondary sex traits and mate attracting displays in sex-role-reversed species are usually more pronounced in females than in males. However, among the 30 samples assessed were not all been amplified. The sex of an individual is recognized from the genes located on sex chromosomes.

The red phalarope Phalaropus fulicarius is a textbook example of a sex-role-reversed species. These sizes were slightlydifferent compare to the finding reported by Dawson et al. This study aims to assess the reliability of those tree primer set to identify the sex of Bali Starling. A DNA test to sex most birds. By using the knowledge of sex identification genes, the breeding program can be applied more successfully. This finding sugested the need to separate the amplicon on acrylimide gel. Biological Letters 43 1: Molecular Ecology Notes 1: However, two of them resolved two bands in acrylimide gel. The same results were reported by Kahn et al. The breeding plumage of female red phalaropes is usually more brightly colored than male plumage, a reversed sexual dichromatism usually associated with sex-role reversal. The sex of an individual is recognized from the genes located on sex chromosomes. For the conservation of bird it important is to determine its sex at the earlier stage. Conventional methods have limitations. Our result, combined with previous observations of brightly colored red phalaropes incubating nests at the same arctic location Igloolik Island, Nunavut, Canada , suggests that plumage dichromatism alone may not be sufficient to distinguish males from females in this breeding population of red phalaropes. It is generally agreed that males are responsible for all incubation and parental care duties, whereas females typically desert males after having completed a clutch and may pair with new males to lay additional clutches. The identification of sex is very important because it is one of keys points on Bali Starling breeding program. Some methods have been developed for sex identification of monomorphic birds, i. It is generally agreed that males are responsible for all incubation and parental care duties, whereas females typically desert males after having completed a clutch and may pair with new males to lay additional clutches sequential polyandry; Dale et al. A simple and universal method for molecular sexing of non-ratite birds. These sizes were in agreement with the study by Griffths et al. Abstract Sex-role reversal, in which males care for offspring, can occur when mate competition is stronger between females than males. Even some of the methods can hurt or even kill the bird Dubiec and M, Most of the results of molecular sexing were in accordance with the sex based on morphological characters. These methods, however, are less or unreliable, time-consuming and expensive.

This stresses the need for more systematic genetic sexing combined with standardized description of intersexual differences in red phalarope plumages.
