| Abstract: | The random amplified polymorphic DNA (RAPD) analysis was used to estimate the genetic relationships and diversity of two brachyuran crab species (Sesarma brockii & Grapsus strigosus) in an artificially developed mangrove ecosystem. Ten arbitrary primers were screened to identify species-specific RAPD markers in S. brockii and G. strigosus. On average about 26% scorable RAPD bands were specific to each species. Gene diversity (H) in S. brockii and G. strigosus was 0.0589±0.0457 and 0.0056±0.0052, respectively. The genetic distance between S. brockii and G. strigosus was 1.2714. Phylogenetic analysis revealed that these two species grouped into separate clusters emphasizing the distinct species status. |
