It is a bit far-fetched, but I would not toss it out entirely. The series is still quite young, so there is no telling what all is going on. I am pretty sure that handedness or whatever that word is isn't actually genetic, though. I do not personally think that eye color is much to go on, either... I do not have the same eye or hair color as anyone in my entire family (dark gold for both; the exact same color, actually... that is why gold is "my" color). They do both have the exact same skin tone, though, which is probably much more significant. Blake, Yang, Pyrrha, and Nora are all slightly darker skinned than Ruby and Weiss.
