Abstract
Tokay gecko (Gekko gecko, Linnaeus 1758) is a small country lizard animal that has a diverse skin color that is decorated with red spots to orange on its back. The study of variations in morphology is very important in various aspects, especially in describing the definition of a species. This study aims to determine the morphological variations based on morphometry and meristic of Gekko gecko in each population. In this study PCA and UPGMA analysis were carried out. The design in the study begins with the measurement phase of 24 morphological characters. The results displayed will be eigenvalue tables, scatter plot graphs and dendograms. The results obtained were then analyzed descriptively. A total of 122 samples of Gekko gecko (male = 81; female = 41) originating from various populations showed a number of character variations between individuals and populations. On certain islands have dominant characters in each population even though these characters are also found in other populations with relatively small values. Gekko gecko in the six populations illustrates overlapping groupings and no significant or dominant character has been seen so that no special character can be found that can be used as a diagnostic character in the Gekko gecko population in a particular population.
