Yes redfox is correct the founding animals to this group were W/C animals from the Rabbit Flat area and i am a locale specific freak when it comes to woma's
Using Alice springs and Tennant creek as the base line of a triangle rabbit flat is the point of that triangle.
Easily found in a goggle search. Its in the NT but close to the WA border.
Hoping if its inheritable and that its a simple ressessive. As i have 4 full siblings to these guys that i hope will be Hets to the trait.
Guess time will tell
