Umblachery breed is an excellent draught cattle of Tamilnadu, noted for its strength and sturdiness especially used in the marshy fields for wed ploughing. Several genetic markers have been used for identification of farm animals. The present study was undertaken to characterize the Umblachery breed with chromosomes. The diploid chromosome number in Umblachery cattle was 2n=60 comprising of 29 pairs of autosomes and one pair of sex chromosomes. All autosomes are acrocentric, the X- chromosome is submetacentric and Y chromosome is acrocentric. C-banding in Umblachery cattle was showed all autosomes with darkly stained centromere but the sex chromosomes were found to be C-band negative.

Abstract


Umblachery breed is an excellent draught cattle of Tamilnadu, noted for its strength and sturdiness especially used in the marshy fields for wed ploughing. Several genetic markers have been used for identification of farm animals. The present study was undertaken to characterize the Umblachery breed with chromosomes. The diploid chromosome number in Umblachery cattle was 2n=60 comprising of 29 pairs of autosomes and one pair of sex chromosomes. All autosomes are acrocentric, the X- chromosome is submetacentric and Y chromosome is acrocentric. C-banding in Umblachery cattle was showed all autosomes with darkly stained centromere but the sex chromosomes were found to be C-band negative.
