It's basically a matter of waiting for a blue eyed mojave, or breeding the normals from the Mojave children to mojaves/BEL.
You're saying that the blue eye trait is recessive or possibly homozygous co-dominant, so if the blue eye gene crossed over in one, wouldn't you have a mojave that was double het for blue eyes, since what you're effectively doing is pulling one of the mutated allelles from the chromosome that would normally need both copies to express the phenotype, and pairing it up with another non-mutated allelle on a different chromosome? This is a new and interesting concept to me, but I'm a little confused about how the cross over phenotypes would be expressed.
