title: Use of beta-actin gene intron 2 as a phylogenetic marker in fish taxonomy.
abstract: Intron 2 of the beta-actin genes from several fish species was sequenced and aligned with a Clustal W program for maximum similarity. From the maximum similarity and phylip data, it was noted that the intron 2 sequences would be useful for establishing a molecular phylogenetic tree and in elucidating the gene flow through evolution, especially at the family level.
