Karyological studies in Kanni Adu Breed of goats

Kanni Adu breed of goats in Tamilnadu were subjected to karyological analysis to study the number and morphometric attributes of the chromosomes. The Karyotype of 2n = 60 chromosomal complements was constructed and their relative length measured. There were 29 pairs of autosomes and one acrocentric X and metacentric Y chromosome. Altered slide preparation techniques and different methods of drying showed no significant differences. Dropping of cell suspension on to slides from a height below 10 cm and possibility of storage of cell suspension in −20°C up to one year are suggested. The X and Y chromosomes shared 5 and 2 per cent of the total chromosomal complement respectively in this breed.
