摘要: 本文报道了|HENG|形目和雀形目6种鸟的核型, 并与已报道的近缘种类进行了比较。结果表明,除个别情况外,种间及属间核型差异不大,这些差异主要是由臂间倒位导致着丝点位置的改变而形成的,从而支持了鸟类核型在进化过程中有较强的保守性这一观点。
Abstract:The karyotypes of 6 species in Charadriiformes and Passeriformes birds were studied they were compared with ralative species that were reported before.The results showed that there were no differences of karyotypes among species and genera,except some special species.The differences were mainly due to the change of centrometric position which was caused by the pericertric in version.Therefore,the results again prove the hypothesis that bird karyotype is exceedingly conservative in the course of evolution.
