Statisticly: 25% Super Hypos; 50% Hypos, 25% Normals
Regarding "Which will be Gee and which will be Salmon?": It will be a polygenic blending like you see with any semi-unrelated breedings. Like breeding two different normals togethers: You could get some that look close to mom.. some inbetween.. some that look close to dad. Cant really lay out those percentages because it is impossible to know, that aspect is dictated by the strength of the genes in each parent.
