The number of the chromosomes in Henan large tail sheep is 2n=54, the karyotypes of male and female sheep are 54, XY and 54, XX, respectively. There are 26 pairs of autosomes and 1 pair of sex-chromosome. Among 26 pairs of autosomes, 3 pairs are metacentric chromosomes, 23 pairs are telocentric chromosomes. X chromosome is the biggest subtelocentric chromosome and Y chromosome is the smallest submetacentric chromosome.

河南大尾寒羊二倍体染色体数目为2n=54，公羊核型54，XY；母羊核型54，XX.27对染色体中包括26对常染色体和1对性染色体，常染色体中有3对为中着丝粒染色体，23对为端着丝粒染色体；性染色体中，X染色体为最大的端着丝粒染色体，Y染色体为最小的中着丝粒染色体。

Primary culture and subculture were adopted using lung cells of a female Elaphodus cephalophus' embryo. A new karyotype and a pair of big telocentric chromosomes were found. The diploid has 48 chromosomes, and the karyotype formula is 2M+2ST+42T+XX. C-banding analysis shows that these chromosomes are homologous with those reported relevant chromosomes. This article is the first to report the polymorphism of Elophodus cephalophus B-chromosomes and studies it's transmitted mechanism.

采用原代培养和传代培养法，对1头毛冠鹿的胚肺组织细胞进行观察，发现一种新的核型，其二倍体染色体数目为2n=48，核型公式为2M+2ST+42T+XX，出现1对大的末端着丝粒染色体，C-带显示该染色体与已报道的相关染色体同源，首次提出毛冠鹿B染色体多态，对其传递机制进行了探讨。
