Technically, all gerudos are half blooded (or less.) Eventually the gerudoes would breed the gerudo species out of existence.
Think about it.
Generation 1 = 100% (original, 100% gerudo, first cursed.)
Gen 2 = 50% (still mostly gerudo)
gen 3 = 25%
gen 4 = 12.5%
Etc, until eventually, you just arent gerudo (or are a very very very small percent gerudo.)
This would tell me that in 100-150 years, its likely the gerudos children would start being male more often because of lack of gerudo blood. Thus, the gerudos no longer would exist.
Or the curse was broken when nabooru became a sage because the gerudos started to be.... nicer. In this case, there would also be no more gerudos and they died out.
Also the gerudos lived in one of the lowest regions of Hyrule, near the lake and also in the desert. This tells me that they may not have been able to go to a mountain to be on the surface, or that they existed at the time of the wind waker but drowned when hyrule was finally washed away. (Hyrule as we know it wasnt even covered with water until the end of the wind waker, you can even see the world from
OoT, hyrule was simply frozen.)
Well there is what i believe to be 3 possibilities.
