This pertains to the Genesis 7 furs, but is really a Gen7/6 proof:
Patch 2 is dominant to Patch1.
Straightforward proof: Patch1 boy (Chretien) mates with Patch2 girl (Mimsygroves). They produce a Patch2 kitten (Novo). When mated with a more recessive fur (Jeri), the breeding pulls the hidden fur - Patch1 - out into the open on the kitten.
This is important because Patch1 is the most dominant fur of the Genesis 6s. We would like to see all of the Gen 7s stack on top of Patch1 if possible.
