Tiger! - Purple Kiwi is dominant to Tiger! - Turquoise.
I'm posting this for Shannon Spoonhunter, who is out and about on a phone and couldn't do it on her phone.
Straightforward proof: Shannon bopped a PurpleKiwi (Justine) together with a Turquoise (Ferrell). They produced a kitten (Jourdaine) which shows the Tiger! - Purple Kiwi. When Jourdaine is mated with a more recessive fur (CONNY showing the Burmilla Chocolate Caramel), the Caramel pulls Jourdaine's hidden, which is the Turquoise. Therefore Purple Kiwi can hide Turquoise, Ergo, Purple Kiwi is dominant to Turquoise.
Thank you so much Shannon for doing this test!
