Abstract

The present study comprised of 25 blood samples from domestic cats were  cultured in duplicates for comparing efficacy of two mitogens i.e. Concanvalin A and Lectin.  Concanvalin A was found to be significantly superior to Lectin. GTG- banding was used for preparation of domestic cat karyograms. Diploid number of chromosomes in domestic cats were found to 2n = 38 consisting of 18 pairs of autosomes and 1 pair of sex chromosomes. The 18 pairs of autosomes were classified into 5 groups as A,B,C,D,E, and F consisting of autosome pairs as Large submetacentric 3 pairs, Large subtelocentrics 4 pairs, Large metacentrics 2 pairs, Small submetacentric and subtelocentrics 4 pairs, Small metacentrics2 pairs and Telocentric or acrocentric 2 pairs, respectively. Whereas ‘X’ chromosome was found to be medium sized subtelomeric and ‘Y’ chromosome was small areocentric.  No major significant abnormalities were reported in the present investigation.
