“…A total of 34 morphometric characters and 9 meristic counts were recorded within each species as descriped by Bagenal (1978), Ezzat et al (1979), Taniguchi et al (1996), Sahu et al (2000), Costa et al (2003) and Doherty and McCarty (2004). Condition factor of each species were measured using the following equation:…”

This study aimed to study the phenotype and genotype differentiation and to compare the amount of differences in phenotype based on morphometric character indices and meristic counts with the amount of differences in genotype based on random amplified polymorphic DNA (RAPD) fingerprinting between two Mugilidae, Flathead grey mullet (Mugil cephalus) and Thinlip grey mullet (Liza ramada). The results showed that there were significant differences in most of the morphometric character indices but no significant differences were detected in most of the meristic counts between M. cephalus and L. ramada. In addition, the euclidean distance between M. cephalus and L. ramada using hierarchical cluster analysis of quantitative phenotype based on morphometric character indices and meristic counts and condition factor was (0.421). Genotype analysis based on RAPD fingerprint showed highly genetic dissimilarity (0.437) between M. cephalus and L. ramada. These results confirmed that the amount of differences in genotype reflected the same amount of differences in phenotype between M. cephalus and L. ramada. Therefore, either phenotype analysis can be use based on a large number of morphometric character indices and meristic counts or genotype analysis based on RAPD fingerprinting to discriminate M. cephalus and L. ramada with the same results.

Variation in phenotype based on morphometric character indices and meristic counts and in genotype based on random amplified polymorphic DNA (RAPD) fingerprinting among different wild and cultured Nile tilapia (Oreochromis niloticus) populations were analyzed phylogenetically to study and compare the amount of differences in phenotype with the amount of differences in genotype and to help assess the degree of phenotypic plasticity shown by these populations. The results revealed that there were significant differences (P≤0.05) in most of morphometric character indices and meristic counts among different wild and cultured Nile tilapia populations tested. Data of genetic similarity coefficients among four populations of Nile tilapia based on RAPD data of all primers used, showed the highest interpopulation genetic similarity (64%) exhibited between Manzalah and Edku Lake populations, while the lowest genetic similarity (37%) was recorded between Manzalah Lake and cultured populations. The hierarchical cluster analysis based on each phenotype and genotype analysis grouped the four populations into two major category groups: Edku Lake, Manzalah Lake and Nile river populations group and cultured population group. Within these major grouping, wild Nile tilapia were grouped close together. Also, Edku Lake population appears to be more similar to that of Manzalah Lake population than that of Nile river population. Moreover, the great concordance between each phylogeny based on phenotype and genotype analysis revealed that the phenotypic plasticity may not be found in the different Nile tilapia populations tested and the relationship among them considered as intraspecific.
