The diploid chromosome number in Rattus (Millardia) meltada pallidior (Ryley) is 52 where all the autosomes are acrocentric, and the sex-chromosomes X and y are metacentric. The X chromosome is the largest in the complement being 13.25 microns and the y chromosome is 6.00 microns in length. The autosomes range in size from 9 microns to 2.57 microns.
