Abstract

We report the finding of the first haploid-diploid-triploid mosaic fish from the family Poeciliidae. The animal was derived from a laboratory cross of a female F1 hybrid of Poecilia mexicana and P. latipinna with a male from an ornamental strain derived from P. mexicana and P. sphenops (Black molly). It was identified because of its unusual pigmentation pattern and molecular methods (flow cytometry, NOR staining) confirmed its mosaic genotype. The mode of mosaic formation and the possible importance for poeciliid fish evolution are discussed.

摘要

我们报告了从花鳉科首次发现的单倍体-二倍体-三倍体嵌合鱼。该动物源自墨西哥花鳉和帆鳍花鳉的雌性F1杂交种与来自源自墨西哥花鳉和黑摩利（黑花鳉）的观赏品系的雄性之间的实验室杂交。它因其不寻常的色素沉着模式而被识别，分子方法（流式细胞术、核仁组织区染色）证实了其嵌合基因型。本文讨论了嵌合体形成的模式以及对花鳉科鱼类进化的可能重要性。
