A lesser is a Lesser platinum, no difference.
A platty is something else. It's a gene on the same loci from Ralph Davis.
btw : I hope you didn't hope that the combo would give you what is on Nerd website. I think your woma is a Type II (like most around). Only the type I can give inferno etc... But the woma lesser combo is still really nice IMO.
I was thinking of doing the same combo with my lesser female, but decided to pair her up with a mojave het ghost. The BEL is one reason, but mostly cause I want more lesser het ghost or at least possible ghost, to move my way on lesser ghost one day.
