“Bayesian concordance analysis of single-copy genes overwhelmingly supports Sequoiadendron as the closest relative of Sequoia…Single-copy trees convey strong support for Sequoiadendron’ (JGL: eg gigantean) ‘as the closest relative of Sequoia’ (JGL: eg sempervirens), ‘suggesting that there was no genome contribution from Metasequoia.” (JGL: They also talk about polyploidy differences and relate it to evolutionary trends.)

JGL Further Comments:
1) Similar single copies of genes but others different-unique creations(common design) or degradation of the initial genome.
2) Polyploidy simpervirens many more copies than gigantea. Possible replication errors or individual design.
3) Controversial common ancestor-if any.
