I don't know yet how it is inhereted. It gets complicated because I would really need to raise all offspring to maturity because the newborns of most johni are born with very vivid orange coloring. I can now differentiate my first and second generation babies at birth, but mainly because I know the histories of the parents as there is some overlap in the color. It is nowhere near as obvious as looking at an albino and normal. It is more like trying to differentiate F1 and an F2 hypo boa constrictors in an F1 x F1 cross.
Last year I bred my second generation orange male to a very dark unrelated female. I still have 3 of the 4 babies and while they are still holding their juvenile colors, only time will tell how dark they will get or if 1 or 2 or 3 of them stay orange. I have more on my web page. It'll take more to pin down the genetics, but it's a start.
:Talking about the Staub strain of high-orange Indian sand boas. Does anyone (or Rick if you're out there) know if the inheritance of this trait was proven to be simple recessive? Thanks.
