Karyotypes of five males and one female scimitar‐horned oryx ( Oryx dammah ) were prepared using lymphocyte and skin cells. CBG‐, GTG‐, and RBG‐banded chromosomes were analysed and the banding patterns were compared with those of cattle, revealing a high level of homoeology except for chromosomes 9, 14, 21, Y, and X. Standard karyotypes are proposed for the scimitar‐horned oryx karyotype, which contains 58 chromosomes with one pair of large submetacentric autosomes and 27 acrocentric autosomal pairs. The X and Y chromosomes are the largest and smallest acrocentrics. The scimitar‐horned oryx chromosome 1 is submetacentric and appears to result from the fusion between ancestral forms of bovid chromosomes numbered 1 and 29 according to the R EADING C ONFERENCE (1980) nomenclature and to ISCNDA 89 if GTG‐banding is used.
