Alright, so I finally got all of the genetic mapping and everything done and here are the results.
Max and Darcy. While you do share the genes that make up your eye color and hair color and so forth, you have no genetic markers in common. You are in no way related.
TJ and Bucky. Same goes for you. While you do have similar genes as far as physical characteristics are concerned, you're not related at all.
This is where things get interested.
Aaron. You are related to neither Clint nor Hansel. You just all happen to look alike. But here's the interesting part.
Based on the various information I could gather after doing the genetic test I have found that Hansel is actually Clint's Great Great Great Great Uncle. I was able to do some family tree research and figured all of this out. It's pretty interesting if you guys want to see it.
