摘要
采用空气干燥法制备骨髓细胞染色体标本 ,报道了雀形目 5科 8种鸟的核型 ,其中八色鸫科为世界首次报道核型的科 .比较研究表明 :臂间倒位和小染色体缺失在所描述类群的染色体进化中起着重要作用 .图版 2表 6参
The karyotypes of 8 species of passerine birds were studied using bone marrow cells with colohicine hypotonic air drying technique. The results indicated: Pitta brachyura 2 n =84; Dicrurus hottentottus 2 n =72; Sturnus nigricollis 2 n =76; Sturnus sericeus 2 n =78; Copsychus saularis 2 n =78; Myiophoneus caeruleus 2 n =78; Garrulax perspicillatus 2 n =76; Parus major 2 n =80. The karyotype of Pittidae was firstly reported. Macrochromosome pericentic inversion and deficiency of microchromosomes were found to play a significant role in karyotype evolution in this family.
