ABSTRACT
Karyotyping is one among the culling parameter used for taking up culling decisions. Cytogenetic screening of breeding bulls has been recommended to screen for chromosomal abnormalities before semen production in artificial insemination. The chromosomal analysis of a Holstein Friesian crossbred bull revealed the presence of acrocentric Y-chromosome, which was further confirmed by CBGbanding. The shape of the Y-chromosome determining that male line used for crossbreeding was from indigenous origin. Karyotyping is a best and reliable technique for the identification of crossbred calves born to the indigenous bulls.
