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.

在突尼斯沿海地区,一方面在两个硬骨种群 (Sardina pilchardus) 和两个寄生co足类种群 (Peroderma cylindricum) 之间和之间进行的遗传分析表明 (l) 所分析的14个基因座在硬骨种群中是单形的; (II) 在被调查的13个基因座中,有3个基因座在co足类种群中具有多态性。从Hardy-Weinberg平衡和基因型同质性的偏差进行的统计测试表明,co足类种群内部和之间存在强烈的基因流。因此,似乎Teleostean (Sardina pilchardus) 和co足类 (Peroderma cylindriicum) 至少在突尼斯海岸上构成了两个同质的taxinomic单位。
