关于2n和n在减数分裂中用法的商榷

Discussion on the Terminology of 2n and n in Meiosis

在科学研究论文、高中生物、大学细胞生物学和遗传学减数分裂教学中,减数分裂I终变期细胞中的染色体数目的表示是用n还是用2n,目前还比较混乱,有的用n表示,但也有的用2n表示。该文通过对减数分裂I终变期细胞染色体行为和数目的分析,认为减数分裂I终变期细胞中的染色体数目应该用2n表示。

The confused usage of terminology 2 n and n in diakinesis stage meiosis I of spore mother cells were found in cell biology and genetics teacher of high school and college, also in the research paper. Based on the analysis of pairing behavior and chromosome number in diakinesis stage meiosis I of spore mother cells, we supported that 2 n is suitable in counting the chromosome number in diakinesis stage meiosis I.
