The number of chromosomal sets that constitute a plant’s genome strongly influences the genetic complexity with which characters are inherited to the next generation determining the limits of strategies for plant breeding. Schie et al. analyzed the genome complexity of a popular ornamental, the garden dahlia. Using a large number of DNA markers it could be shown that the dahlia genome comprises eight copies (e.g. dahlias are octoploids) and that these eight copies freely recombine for most parts of the genome with only some segments that are inherited as separate sub genomes.
