The study was conducted to karyotype and prepare idiogram of Jayawadagi goats. Blood samples for short term lymphocyte culture were collected from 5 male and 5 female Jayawadagi goats. The diploid chromosome number was found to be 60, consisting of 29 pairs of acrocentric autosomes and a pair of allosomes (X and Y). The X chromosome was the longest acrocentric and Y chromosome was found to be sub metacentric. The mean mitotic drive was 57.95±1.16 and 60.2±2.38 per cent in males and females, respectively. The mean relative length of autosome varied from 1.81±0.08 to 4.79±0.09 in females and 1.46±0.17 to 4.11±0.44 in males. The relative length of X- chromosome in females was 5.24±0.19 and that in males was 4.13±0.63, whereas Y- chromosome had a relative length of 1.40±0.24. The mean values of Arms ratio, Centromeric Index and Morphological Index was 3.09, 30.00 and 712.49, respectively. This karyological study indicated the normal chromosomal complement in studied Jayawadagi goats.
