Phal primary hybrid questions.

[Fairorchids]

The degree of pod parent dominance may vary from genus to genus. Two examples that I have witnessed firsthand:

Rhynchostylis gigantea x Neofinetia falcata (= Vandachostylis Pinky)
Plant size & flower shape clearly shows which was used as the pod parent.

Paphiopedilum Nitens (= insigne x villosum)
It is very clear from the flower shape, which species was used as the pod parent. However, Paph insigne always dominates for color.
