Abstract

The diplord (2n) chromosome number of Meriones libycus syrius from Saudi Arabia is 44; the fundamental number (FN) is 78 and the fundamental number of autosomes (FNa) is 74. The autosomes consist of 11 pairs of metacentric, 5 pairs of submetacentric and 5 pairs of acrocentric chromosomes. The X chromosome is the second largest metacentric and the Y is the smallest metacentric element. These findings differ from those previously published for this species.
