Cytogenetic characterization of Malaimadu cattle
A Sakthivel Selvan, V Harshini, Yathish HM and SMK Karthickeyan
Twenty Malaimadu cattle from its breeding tract were utilized to study the chromosome profile through short-term lymphocyte culture method. The diploid chromosome number was 60. All the 29 pairs of autosome were acrocentric, while X- was sub-metacentric and Y was acrocentric. The mean relative length of autosomes ranged from 1.76 to 5.44. The relative contribution of X and Y-chromosome was 5.12 ± 0.26 and 1.76 ± 0.08. The arm ratio and centromeric index of X-chromosome were 1.77 and 0.36 respectively. The chromosome banding showed C-positive dark band heterochromatin in all the acrocentric autosome. The present study revealed that the chromosome architecture of Malaimadu cattle was similar to that of the other registered breeds of indigenous cattle.
