细胞遗传学被认为是了解物种基本遗传和基因组问题的基本工具，对物种间和种内多态性的描述做出了巨大贡献。事实上，细胞遗传学是第一个被用来提出狐猴（双翅目：狐猴科）是一个隐种复合体的方法之一。在阿根廷阿纳斯塔法（Anastrepha fraterculus）居群中发现了不同的性染色体形态变异。然而，由于性染色体的这种高度结构变异性并不构成生殖障碍，因此它们在物种形成中的作用尚未被揭示。这篇综述提供了一个更新的一般方面的细胞遗传学在阿根廷阿纳斯塔法兄弟群体，重点是流行的X-Y排列。
Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level. In fact, cytogenetics was one of the first approaches used to propose Anastrepha fraterculus (Diptera: Tephritidae) as a complex of cryptic species. Different morphological variants of sex chromosomes have been reported among Argentinean populations of Anastrepha fraterculus. However, since this high structural variability in sex chromosomes does not pose a reproductive barrier, their role in speciation is yet to be unveiled. This review provides an update on general aspects of cytogenetics in Argentinean Anastrepha fraterculus populations, focused on the prevalence of X-Y arrangements.
