1 to find out the resemblance and relationship between fasciolid species.
2000) and due to the presence of intra-species morphometric differences and significant overlaps of these indices between the two species, it is emphasized that morphometric measurements alone are insufficient for differential diagnosis of the fasciolid species.
Phenotypic analysis has been used most frequently to study the systematics of fasciolids infecting different vertebrate host species.
Moreover emphasis was laid on the comparison of five most valuable parameters to analyze phenotypic variations in fasciolids.
Besides, information gathered will provide taxonomical status of fasciolids established in different geographical regions of Pakistan.
In the present study five useful and most favorably used differentiating morphometrical parameters (BL, BW, BL/BW, VS- Vit, VS-Post) for species differentiation were considered for phenotypic characterization of fasciolids (Valero et al.
The dendrogram represents the similarities among the different fasciolids (Fig.
Besides, differences in morphometry of organs of fasciolids can be influenced by intensity of infection, host species, age and immune reactions due to a possible previous exposure to the infection.
