Ayup, I was just thinking out loud.<br/><br/>Although, how do you explain True Red Eyes? Another, separate gene, that is only 'activated' when the user has the regular bloodline? And recessive too, explaining its rarity. Everyone has this gene, but it's just 'filler' unless you also have the Red Eyes gene.<br/><br/>In that event, it is extremely unlikely that Tashi could produce another True Red Eyes.<br/><br/>The Mibu clan would need to be very careful indeed, if they are so meddlesome as to dictate his 'love life.' Ideally, they would need to find someone with a double-recessive 'True Red Eyes' gene, regardless of whether or not they have the regular Red Eyes gene. Now... given that we can assume the human genome hasn't been mapped out in the Naruto verse, we could say that the Mibu have no way of knowing what sort of genes people have except through their traits.<br/><br/>Given that Tashi is the first True Red Eyes that they've seen in many generations and they have no way of knowing who has the double-recessive True Red Eyes gene... The smart thing to do would be to pair Tashi up with his<strong>siblings</strong>, since there is a chance they will have the same exact combination of (Aa or AA) Red Eyes... and (aa) True Red Eyes.<br/><br/>So, question- Where are Tashi's parents? Did they have any other children? :P<br/><br/>Or how else would True Red Eyes work... appearing only once every few generations? Hey, my theory makes more sense than<strong>implanting your sibling's eyes makes them stronger.</strong>
