Abstract
New records of chromosome numbers were found in Indian muntjacs (Muntiacus muntjak) and fea's muntjacs (M. feae) in Thailand. Cytogenetics of endangered wildlife species, Indian muntjacs and fea's muntjacs were examined by lymphocyte culture of whole blood. The karyotypes of 3 female Indian muntjacs indicated chromosome number of 2n=6. The X chromosome was fused to the p-arm of chromosome paired 3. The 2 male karyotypes showed chromosome number of 2n=7 and the first finding out of 2n=9. The 2n=9 might originated from breakages of 2 large metacentrics in the 2n=7 to become 2 large acrocentrics, as the 2 fragments to become the 2 large telocentrics in the 2n=9. Karyotypes of 4 female fea's muntjacs indicated chromosome number of 2n=13 and the first discovery of 2n=12 and 2n=14. The 2n=12 and 2n=13 originated from fusion of chromosome paired 7 and chromosome paired 2 in the 2n=14. The karyotypes of the 2 males revealed chromosome number of 2n=14. The X chromosome was fused to the p-arm of the acrocentric chromosome paired 1 and the Y chromosome was the small submetacentric. The variation of chromosome numbers was caused from chromosome breakages and fusions in this genus.
