Genetic Diversity (Or Lack Thereof)

They're not all in one place all that often, so when I caught THESE seven boys hanging out together at church the other day, I had to take a picture:

Colby said "Mom, I just realized that our Sunday School class has two sets of identical twins, and one set of identical triplets!"

You JUST figured that out?  It's been that way since pre-school.  Six years ago.  But, okay.  Yes.  He just realized.

Seven boys.  Three genetic codes.

That is pretty cool.
