ABSTRACT

Cytogenetic studies were conducted on a total of 60 Vizianagaram sheep maintained at the Livestock Research Station, Garividi and sheep managed by farmers in and around Srikakulam District of Andhra Pradesh. Short term lymphocyte culture technique was adopted. The diploid chromosome number was found to be 54 (2n = 54, XY). The first three pairs of the autosomes were submetacentric and the remaining 23 pairs of autosomes were acrocentric. The X chromosome was the longest acrocentric, while the Y- chromosome was the smallest biarmed. The mean relative length for the autosomes ranged from 1.54 ± 0.04 to 9.59 ± 0.12 per cent, While the mean relative length of X and Y chromosomes were 5.06 ± 0.02 and 1.81 ± 0.17, percent respectively. The mean arm ratios, centromeric indices and morphological indices varied from 1.31 ± 0.07 to 1.24 ± 0.07, 0.545 ± 0.04 to 0.565 ± 0.07 and 7.59 ± 0.01 to 5.36 ± 0.01, respectively.
