Abstract

Background: To characterize the chromosomal complement of Nandidurga goats. 
Methods: Blood samples for short term lymphocyte culture were collected from 5 bucks and 5 does from its breeding tract and then mitotic chromosomal spreads were accomplished. 
Result: The diploid chromosome number was found to be 60, consisting of 58 acrocentric autosomes and 2 sex chromosomes (X and Y). The X chromosome was found to be the longest acrocentric and Y chromosome was found to be sub metacentric. The mean mitotic drive was 64.5±2.01 and 63.15±1.30 percent in bucks and does, respectively. The mean relative length of autosomes varied from 2.08±0.24 to 4.81±0.12 in does and 2.09±0.09 to 4.70±0.11in bucks. The relative length of X chromosome in does was 5.14±0.17 and that in bucks was 4.92±0.21, whereas Y chromosome had a relative length of 1.99±0.20. The mean Arms Ratio, Centromeric Index and Morphological Index were 2.47, 31.62 and 396.14, respectively. This cytogenetic analysis indicates the normal chromosomal complement in the studied Nandidurga goats.
