Chromosomes in the African frog genus Tomopterna (Pyxicephalidae) and probing the origin of tetraploid Tomopterna tandyi.

The article probes the origin of tetraploid Tomopterna tandyi and tests the hypothesis that T. tandyi is an allotetraploid species based on the revised taxonomy and chromosomes in the African frog genus Tomopterna (Pyxicephalidae). The summary distinguished tetraploid Tomoptera from diploids by counting the chromosomes and analyzed rRNA sequences for all the Tomoptera species. It determined haplotype networks for gene fragments, divergence ages, isozymes and Tomoptera advertisement calls.
