| 摘 要： | 采用外周血淋巴细胞培养法，对布尔山羊的染色体核型进行了分析。结果表明，布尔山羊的二倍体染色体数目为2n=60，公羊核型为60，XY；母羊核型为60，XX。共有29对常染色体和1对性染色体。所有常染色体均为端部着丝点染色体；X染色体为第二大的端部着丝点染色体，Y染色体为最小的天是唯一的中部着丝点染色体。研究发现，布尔山羊存在1.7％的三倍体和5.9％的四倍体。

| Abstract: | In this paper，chromosomal karyotype of Boer goat was studied by using the peripheral blood lymphocyte culture method。The results showed that the number of the chromosomes in Boer goat was 2n＝60。The karyotypes of male and female goat were 60，XY and 60，XX respectively。All 29 pairs of autosomes were acrocentric chromosomes;X chromosome was the second largest acrocentric chromosome and Y was the smallest and the only one metacentric chromosome in all chromosomes。The triploid and tetraploid with the occurrence rates 1.7% and 5.0% respectively were observed in Boer goat。 |
