摘要
Abstract
The mitotic and meiotic chromosomes of Apod emus peninsulae from Mt. Changbai, Jilin Province (A. P. Preator) and M t. Tai, Shandong Province (A. P. Sowerbyi), and Mt. Qinling, Shaanxi Province (A. P. Sowerbyi), China are d escribed. The A chromosomes of two subspecies A. Peninsulae are identical, I. E. 4 8 teloc entric chromosomes. There are differences in the number and types of B chromoso mes between three populations. One to three medium size metacentric B chromosome s appeared in A. P. Preator, and five to fourteen (two types-one medium size met acentric and four to thirteen dot-like B chromosomes) in A. P. Sowerbyi from Mt. Tai and 0～1(telocentric) in A. P. Sowerbyi from Mt. Qinling. Two level s of B chromosome numerical variation, inter- and intraindividual, were found in two sub species.关键词
