Summary

The chromosome morphology of Berari goat of Vidarbha region of Maharashtra was studied. The chromosomal compliment of Berari goat consisted of diploid chromosome number 2n=60. All the autosomes were acrocentric, X chromosome was identified as the second largest chromosome and Y chromosome was found to be smallest and metacentric. The mean mitotic drive in female was found to be 51.22±0.65 while in male it was 47.94±0.94. The mean mitotic drive irrespective of sex was found to be 49.58±0.61. The mean mitotic index in female was found to be 6.59±0.58 while in male it was 5.29±0.85. The mean mitotic index irrespective of sex was found to be 5.94±0.13.
