<strong>Comparison</strong> <strong>of</strong> <strong>RAPD</strong> <strong>and</strong> <strong>PCR</strong>-<strong>RFLP</strong> <strong>markers</strong> <strong>for</strong> <strong>classification</strong> <strong>and</strong> taxonomic studies 191<br />

Intraspecific variation (within each species):<br />

The average percentages <strong>of</strong> monomorphic b<strong>and</strong>s within each species are<br />

shown in Table (1). Among all species, the average percentages <strong>of</strong> monomorphic<br />

b<strong>and</strong>s were 67.0% <strong>and</strong> 61.0% <strong>for</strong> <strong>RAPD</strong> <strong>and</strong> <strong>RFLP</strong> analyses, respectively (Table 2).<br />

These overall similarity values indicated the detectability <strong>of</strong> polymorphism with the<br />

two kinds <strong>of</strong> molecular marker systems. The intraspecific variation within the three<br />

ant species, C. maculatus, M. pharoensis <strong>and</strong> C. bicolor, was shown in Table (1).<br />

Interspecific variation (between species):<br />

The average percentages <strong>of</strong> monomorphic b<strong>and</strong>s between species are shown in<br />

Table (2). Between all species, the average percentages <strong>of</strong> monomorphic b<strong>and</strong>s were<br />

33.0% <strong>and</strong> 39.0% <strong>for</strong> <strong>RAPD</strong> <strong>and</strong> <strong>RFLP</strong> analyses, respectively (Table 2). The average<br />

percentages <strong>of</strong> polymorphic b<strong>and</strong>s were higher between M. pharoensis <strong>and</strong> C.<br />

maculatus (18.4% <strong>and</strong> 15.8% <strong>for</strong> <strong>RAPD</strong> <strong>and</strong> <strong>RFLP</strong>, respectively) than between M.<br />

pharoensis <strong>and</strong> C. bicolor (9.3% <strong>and</strong> 14.8% <strong>for</strong> <strong>RAPD</strong> <strong>and</strong> <strong>RFLP</strong>, respectively) <strong>and</strong><br />

between C. maculatus <strong>and</strong> C. bicolor (11.3% <strong>and</strong> 5.4% <strong>for</strong> <strong>RAPD</strong> <strong>and</strong> <strong>RFLP</strong>,<br />

respectively) (Table 2). These overall dissimilarity values indicated the detectability<br />

<strong>of</strong> polymorphism with the two kinds <strong>of</strong> molecular marker systems. The interspecific<br />

variation between the three ant species, C. maculatus, M. pharoensis <strong>and</strong> C. bicolor,<br />

was shown in Table (2).<br />
