对过去50年来细胞学和细胞遗传学数据在分类学决策和生物系统研究中的价值证据的现状进行了调查。考虑的主要标题是染色体数量、基因组大小、染色体形态、染色体染色特征。关于染色体和基因组在细胞中的配置，以及染色体的行为和同源性，主要结论是，细胞遗传学和分子生物学(分子细胞遗传学)边界上的许多令人兴奋的新发展正在产生大量具有巨大分类学和进化重要性的新数据，但为了使这些数据产生充分的影响，它们必须与传统细胞学数据充分结合，而传统细胞学数据仍然是一如既往的迫切需要。
The status of cytological and cytogenetic data as evidence of value in taxonomic decisionmaking and biosystematic investigations over the past 50 years is surveyed. The main headings considered are chromosome number, genome size, chromosome morphology, chromosome staining characteristics. chromosome and genome disposition in the cell, and chromosome behaviour and homology, The main conclusions are that many of the exciting new developments at the borders of cytogenetics and molecular biology (molecular cytogenetics) are producing a wealth of new data of enormous taxonomic and evolutionary importance, but that for these to reach their full impact it is essential that they are fully integrated with traditional cytological data, the need for which remains as great as ever.
