Study on the karyotype and C-banding of chromosome in Haimen White goat

The karyotype and C banding of Haimen White goat breed were investigated with the peripheral blood lymphocyte culture and chromosome banding techniques.The results showed that the diploid chromosome number of Haimen White goat breed was 2 n =60.The autosomes and the X chromosome were telocentric chromosomes.The size of X chromosome was between No.1 and No.2 chromosomes.The Y chromosome was the smallest metacentric chromosome.The karyotype of buck was 60,XY and the karyotype of ewe was 60,XX.C bands of most autosomal and X chromosome,Y chromosome were exclusively centromerically located,but the size of C banded region was different among different chromosomes.
