Phylogenetic Analysis of Snake Using Cytochrome b Gene Sequence

Abstract

Phylogenetic analysis of two species of snake Eryx colubrinus loveridgei and Ptyas mucosus was investigated using the gene encoding cytochrome b. The nucleotide sequences of complete and partial mtDNA cytochrome b were determined in numerous specimens. Sequence divergence between species and genera was evenly distributed in the cytochrome b gene but rather high compared to reports for other fish species. Phylogenetic analyses on complete cytochrome b were used to study the relationships among the considered species. The molecular phylogeny of sample was determined by analyzing cytochrome b gene sequences. On the basis of position of sequence of the given python sample in the phylogenetic tree, the sample showed closest similarity with Eryx colubrinus loveridgei and Ptyas mucosus.
