Saleem S.D., Al-Hassan L.A.J., Melkonian M.K., 1988. Morphological variance and enzyme heterozygosity in Eleutheronema tetradactylum and Strongylura strongylura collected from Khor al-Zubair area, Basrah, Iraq. Acta Ichthyol. Piscat. 18 (1): 71-78.

Eleutheronema tetradactylum and Strongylura strongylura were studied in testing the association of enzyme heterozygosity with the decreased morphological variance. Six polymorphic loci and three meristic characters were used in this test. The results shown that such a relationship although observed by several others workers may not be common one and hence such hypothesis was not confined.
