Chromosomal study of desi pig.

In present study on Indian domestic pig revealed modal chromosome number 2n=38. The number and morphology were same in the male and female pig except for that of the sex chromosomes. Among these there were 7 pairs of submetacentric (1–7), 5 pairs of metacentric (8–12), 6 pairs of acrocentric (13–18) and one pair of sex chromosomes. The X chromosome was large submetacentric However, Y chromosome was metacentric and smallest one in the chromosome complement. Conventionally stained preparation permitted the identification of chromosome pair no. 1 and the chromosome no. 13 based on length and centromere position. The chromosome pair no. 8 and 10 showed an unstained region nears the centromere in all breeds. Unstained region in chromosome 8 was more distinct and noted easily than chromosome no. 10.
