大额牛与云南黄牛杂交公牛的染色体核型与G-带分析
Ananlysis on Karyotype and G-banding of Chromosomes in Male Hybrid of B.Frontalis×Yunnan Bos Taurus
摘要
Abstract
The chromosome samples and G-banding samples were made by peripheral blood lymphocyte culture to analyze the karyotype and G-banding pattern of the chromosomes in male hybrid of B.Frontalis×Yunnan Bos Taurus.Results showed that the number of the chromosomes in the male hybrid of B.Frontalis×Yunnan Bos Taurus was 59.There were 2×28＋1 autosomes and 1 pair of sex-chromosome.Among 2×28＋1 autosomes,t（2＋28）was submetacentric chromosome,the others 2×27＋1＋1 autosomes were telocentric chromosomes.X chromosome was submetacentric chromosome,Y chromosome was a small telocentric chromosomes.The number of the chromosomes in the male hybrid of B.Frontalis×Yunnan Bos Taurus was 59,and the karyotype was 59,-2,-28,＋t（2∶28）,XY.关键词
