ABSTRACT

The present karyotype analysis was carried out on 15 females and 15 males of Large White Yorkshire crossbred and non-descript pigs to study their cytogenetic profile and morphometric measurements by using short term leukocyte culture technique. The diploid chromosome number (2n) in both the breeds was found to be 38 with a fundamental number of 64 as in exotic.The least squares mean relative length of autosomes in Large White Yorkshire crossbred pigs ranged from 2.80±0.17 to 10.85±0.17 and the values for non-descript pigs from 2.88±0.10 to 11.03±0.18. The relative contribution of X and Y-chromosome in Large White Yorkshire crossbred pigs was 4.66±0.15 and 2.05±0.17, whereas these values were 4.81±0.17 and 2.19±0.17 in non-descript pigs respectively. The overall mean arm ratio of autosomes ranged from 1.01±0.03 to 2.45±0.03 and 1.02±0.01 to 2.43±0.02 in Large White Yorkshire crossbred females and males respectively. The mean centromeric indices of autosomes differs from 0.50±0.04 to 0.71±0.02 in females and 0.51±0.02 to 0.72±0.03 in males of Large White Yorkshire crossbred pigs. The average morphological index value of autosomes ranged from 2.43±0.06 to 7.29±0.11 in females and 2.41±0.05 to 7.31±0.12 in males of Large White Yorkshire crossbred pigs.
