Abstract

Abstract: In this paper, chromosomal karyotype of Wushen horse in Inner Mongolia was studied by using the peripheral blood lymphocytes culture method and conventional chromosome analysis techniques. The results showed that the diploid chromosome number of Wushen horse was 2n=64.The chromosome karyotypes of male and female horse were 64,XY and 64,XX. Among 31 pairs of autosomes, of which 13 pairs were met centric or submetacentric and 18 pairs acrocentric chromosomes, X chromosome was larger submetacentric chromosome and Y was the smallest acrocentric chromosome. Karyotypes of Wushen horse may lay a foundation of insitu hybridization and location of gene.

Key words: Wushen horse, Chromosome, Karyotype
