Genomic analysis of diploid plants.

The numerical analysis of meiosis in the triploid hybrid between an induced autotetraploid and a related diploid provides the basis for investigations of the genomic relationships of diploid species based on chromosome pairing. It is also possible to make legitimate comparisons between different triploid hybrids of this type so that the genomic relationships can be converted into measures of phylogenetic distance for taxa where only diploids are known.
