I had the same info as Richard, though I can’t vouch for it’s accuracy.
That’s why I was skeptical. I don’t think it’s possible for Costata x Rossey 2 to produce a PVNA. One possible explanation that I offered is that the tree is mislabeled.
It also seemed suspicious that two siblings differed so dramatically but I get that it happens. My two granddaughters are blond and brunette; my two grandsons are blond and redhead.
