摘要：

The genome size and sex of the Egyptian Vulture (Neophron percnopterus), a sexually monomorphic bird, were identified from blood samples by the use of flow cytometry (FCM). This technique allowed evaluation of the slightly higher amount of DNA content in the homogametic male compared to that of the heterogametic female. A karyotypic analysis also was performed in order to confirm the FCM results. Sex identification by both FCM and cytogenetic analyses was concordant in all cases. The average DNA content was estimated to be 5.6% higher in males than in females.
