✦ Synopsis
Two parrot species, Amazona amazonica and A. aestiva, submitted to cytogenetic analysis presented a diploid chromosome number of 2n-70 (20M + 50m). With the C-banding pattern, the cells of female specimens showed an almost totally heterochromatic W chromosome. No chromosome differences were observed in the two species studied.
