Duplicate gene expression in diploid and tetraploid loaches (Cypriniformes, Cobitidae)

Stephen D. Ferris, Gregory S. Whitt

Research output: Contribution to journalArticlepeer-review


Botia macracantha and B. modesta have been demonstrated to be tetraploid species on the basis of their karyotypes and on the basis of the expression of a number of isozymes encoded by duplicate loci. A rather low percentage of duplicate loci was detected by electrophoresis, compared to that for other tetraploid Cypriniformes. Several hypotheses have been advanced to account for the low levels of duplicate gene expression observed. Lastly, many of the duplicate loci have diverged to unique patterns of expressions in different tissues or different levels of activity within a single tissue.
