| Abstract: | Phylogenetic relationships among two species
of seahorses (Hippocampus kuda & H. trimaculatus) and one species of pipe
fish (Syngnathoides biaculeatus)
from Gulf of Mannar were
analysed using cytochrome b gene (cyt b)
sequence data (Acc. No. EF
189158 & EF 189167). The genetic distance value
between
H. kuda and H. trimaculatus was found to be 0.155; while
between H. kuda and S. biaculeatus, it was 0.256, and between
H. trimaculatus and S. biaculeatus, 0.290. The percentage of
identical pairs between H. kuda and H. trimaculatus was 85.90, and between H. kuda and S. biaculeatus, 79.19. The percentage of transition
and transversion between two seahorse species (H. kuda & H. trimaculatus)
was lesser than between seahorse and pipe
fish (S. biaculeatus).
The results suggested that further phylogenetic studies are required to
determine the genetic relationship in all Indian seahorse species. |
