A karyological investigation was carried out on 16 Jersey X Sahiwal cattle maintained at Department of Livestock Production and Management, College of Veterinary Science, Tirupati to know their chromosomal architecture. Short-term lymphocyte culture technique was employed for obtaining the metaphase chromosomes. Chromosomes of thirty well spread metaphases from each animal with a total of 480 metaphase spreads from Jersey X Sahiwal Crossbred cattle were screened for chromosomal count and ten metaphases from each animal were taken for karyotyping. The modal diploid chromosome number (2n) in Jersey X Sahiwal cattle was found to be 60. All the autosomes were acrocentric and X chromosome was submetacentric in nature. The Y chromosome was submetacentric in Jersey X Sahiwal.
