After some research and some mining of this forum I have uncovered that if the parents of a child with ursine coat are fawn or wine they must have some sort of G value eye color

Also I have found out and this is where I get stuck, the size of the off spring = Parents Avg + .875x where x can be any where between -16 to +16 but i have not uncovered what causes x..

These results come from a horde of about 100 meeroos, and i am just throwing out my findings, have others noticed this? or am I way off?
