摘要
Several eukaryotes, including maize, yeast and Xenopus, are degenerate polyploids formed by relatively recent whole-genome duplications. Ohno's conjecture that more ancient genome duplications occurred in an ancestor of vertebrates is probably at least partly true but the present shortage of gene sequence and map information from vertebrates makes it difficult to either prove or disprove this hypothesis. Candidate paralogous segments in mammalian genomes have been identified but the lack of statistical rigour means that many of the proposals in the literature are probably artefacts.
