The Bactrian camel, guanaco, and llama all have a diploid chromosome number of 74 and a karyotype consisting of three pairs of submetacentric and 33 pairs of acrocentric autosomes, a large submetacentric X and a very small acrocentric Y. There were no differences in either G- or C-band patterns among these three species. The small arms of acrocentric chromosomes were C-band positive and interstitial C-bands were associated with the centromere of the submetacentric chromosomes. The camel had five pairs of nucleolar organizing chromosomes and the guanaco and llama exhibited six. The identical patterns in chromosome linear differentiation for the Camelidae suggests that their karyotype has been highly stable for millions of years.
