A genetic analysis realized, on Tunisian coasts, within and between two populations of a Teleostean (Sardina pilchardus) on one hand, and two populations of their parasitic Copepods (Peroderma cylindricum) on the other hand, reveal that: (l) the 14 loci analysed are monomorphic in the Teleostean populations; (II) 3 loci among 13 investigated are polymorphic in the Copepod populations. Statistical tests from deviations of Hardy-Weinberg equilibrium and genotypic homogeneity show the existence of strong gene flows within and between Copepod populations. Thus, it seems that the Teleostean (Sardina pilchardus) and the Copepod (Peroderma cylindricum) constitute at least on Tunisian coasts, two homogeneous taxinomic units.
在突尼斯海岸对一种硬骨鱼(沙丁鱼)的两个种群内部以及它们之间,以及对其寄生桡足类动物(圆柱形皮氏桡足类)的两个种群进行的基因分析表明:(1)在所分析的硬骨鱼种群中,14个基因座是单态的;(2)在13个被研究的基因座中,有3个在桡足类种群中是多态的。对哈迪 - 温伯格平衡偏差和基因型同质性的统计检验表明,桡足类种群内部以及它们之间存在强烈的基因流动。因此,似乎硬骨鱼(沙丁鱼)和桡足类动物(圆柱形皮氏桡足类)至少在突尼斯海岸构成了两个同质的分类单元。
