Cytogenetics studies in domestic animal are
gaining importance because of their genetics and implication in
breeding programmes. The present study describes the
chromosome number and karyotypic characteristics of Ganjia
sheep and comparison between males and females breeds. We
adopt the method of cultivating somatic cells, and analyzed the
chromosome karyotype of the Ganjia sheep. The result
indicates the diploid chromosome of the Gangia sheep is 2n=54,
in which 26 pairs of autosomes and a pair of sex chromosome
were observed. Result indicates all autosomes are tip silk. The X
chromosome was acrocentric and largest except the first three
pairs that were metacentric. The Y chromosome was the
smallest, biarmed and probably metacentric chromosome.
