Hmm, the eyes in that Twin Snakes shot look gray to me, but then the whole game has some weird blue filter over it, so who knows. As for MGS2, only his Pliskin identity seems to have the green eyes (contacts?). Are there any images of him in his normal guise that display blue eyes?

I'm not arguing that Solid Snake isn't the "recessive" clone, just that eye/hair color doesn't make for a strong case, due to the very inconsistencies in the games that you mention. Solid Snake's article has references for his blue eye color, and they are specifically stated to be "blue-gray" in MGS4 (the latest appearance of the character takes precedence). Maybe Kojima made Old Snake's eyes blue to match Big Boss in MGS3, rather than the other way round? Although Solid did have a blue pixel for an eye in 1987's MG1.

I'm no genetics major either, but I do have a grounding in the subject. However, I fear I may have opened a whole can of worms in that regard. As you've demonstrated, it's not as simple as "blue-eyed clone = recessive clone", because only a single "parent" exists in this case. Alleles work in pairs, and if Big Boss has a recessive trait, he must have two recessive alleles for that particular gene, one on each DNA strand. Therefore, no clone can inherit a dominant allele from Big Boss in that instance because none exists. They can't leave it blank for the "dominant" clone, so he would also inherit that recessive trait too. The "recessive" clone would only differ by expressing traits coded by genes for which Big Boss had a dominant-recessive allele pair. As you can see, it gets pretty complex, which is why I dismiss the science in the games as pertaining to who is the "dominant" or "recessive" clone.

Big Boss's official biography doesn't contain any Hawaii/WWII/Japanese ancestry info. That originated in Millennium Books' strategy guide.
