Great point ES, which makes me want to ask a question thats been in the back of my mind. What of two plants that consist of the same ancestry % wise but through different parents? I'll try to elaborate.
Lets say we have three species: Cattleya a, Cattleya b, and Cattleya c.
- Cattleya ab and Cattleya bc are produced, and hybridized, creating Cattleya abbc¹
- Cattleya ac is produced, and bred with Cattleya b, producing Cattleya abc
- Cattleya abc is then bred again with Cattleya b, producing Cattleya abbc²
Would those two resulting plants, although coming from parents that are all genetically distinct from eachother, genetically the same plant? This might seem a little absurd, but I've seen a lot of re-breeding done of Clowesia rosea and Clowesia warczewitzii with their hybrid progeny and have wondered if this has happened before.
