摘　　要：本文对家燕和金腰燕的核型、C 带和 Ag-NORs 带进行了比较研究。结果表明,两者的核型基本一致。核型公式:2n=80=2M+4ST+zMwSM+2M+2ST+2SM+8T+2M+56mT/D。但两者在染色体的相对长度、W 染色体大小、G 带带型、Ag-NORs 的数目和分布均存在着差异。文中在家燕 No.1、7、W 染色体和金腰燕 No.1、6、7染色体的形态划分,金腰燕 W 染色体的确定及其染色体数目等方面,均与卞小庄、李庆伟的结果不同。A comparative study on karyotype and C-band and Ag-NOR,of house swallow and red-rumped swallow has been made.The result shows that the karyotype of them are similar,and their karyotypical formulae is 2n=80=2M+4ST+zMwSM+2M+2ST+2SM+8T+2M+56mT/D.But they are different in the relative length of chromosomes,the size of W chromosome,C-band patterns and the number and distribution of Ag-NORs.The result in this paper is different from that of Mr.Bian and Mr. Li in the types of No.1,7,W chromosomes of house swallow and No.1,6,7 chromosomes of red-rumped swallow and the determination of W chromosome and diploid number of red-rumped swallow.
