Abstract
The genome of an endangered avian species the whooping crane (Grus americans) has been examined using the methods of karyotype analysis, cytoflorometry, and analytical ultracentrifugatlon. This species has a karyotype (2n = 62) common to other crai species previously examined with five autosomal pal and one sex chromosome pair as the macrochromsomes, and a large number of mlcrochromeomes. So chromosomes are hateromorphic in females permitting sexing by means of chromosome analysis. The DN buoyant density in neutral CsCl reveals the presence two heavy satellite bands, an uncommon finding who compared to previous studies of avian DNA.
