Think of it as a morph.
Suri X Hog Isle for instance. The F1 are 50%/50%
Now breed one of the 50-50 to a pure Suri.
Some of the babies could get NO Hog Isle genes from the cross and actually be 100% suri. However there is no way to know. As a result the babies are labeled as 75% Suri.
If you look at litters or clutches from two F1 animals, the F2 offspring usually have some that look like the F1, some that look almost like the pure of the patriarch (or more traits) and some look like a pure example of the matriarch (or more traits).
So say you wanted a Hypo Suri, and started by breeding Salmon X Suriname. Take Hypo babies with the most Suriname traits and keep breeding them to Pure Surinames each generation, eventually you would not be able to tell it from a true Suriname Hypo.
