My brother recently caught the blue headed morph of the green frog (Rana clamitans. I tried looking up infomation and I could find much other than its a morph. I was just wondering how common is this trait in the wild and in the pet trade and is it genetic and if it is what type of trait is it? resecive? co-dominat? Anyother infomation would be greatly appricated, thanks. i'll post pictures later.
