A cross with alterna was a base cross for alot of work done by Brent Green & HDEAN you can see some of the results at Henry's site....look for multi crosses with holbrooki alterna as part of the heritage....I believe that a very strange type of T amelanism or hypomelanism popped up out of these later and made some knockout animals...
And to the triangulum....
There was a guy locally that I think produced some triangulum x elapsoides offspring...it wasn't as easy as you would believe seeing as how that cross is responsible for creating a huge expanse of intergrades from MD to NC....at least the latest DNA work seems to prove this. Strange how they intergrade in some regions and in others (N.GA, S.KY, N.AL) they occur sympatric state?
