You’ve explained DNA to the kids (and maybe even used our LEGO analogy to make it stick). Now it’s time to show instead of tell by checking out 3 very observable traits brought to you by good ol’ DNA.

A Family Affair: Height
Totes an observable trait: If two parents are tall, odds are their kids will be tall. And if both parents are short, they’ll be short. So you can blame (or thank) your parents for your stature.
Grab a tape measure and compare stats. If grandparents are around, measure them too, or call them up and have the kids ask their height. Get aunts and uncles in on the fun too. Of course kids won’t know their full height until they are all grown-up, but it’s still a great exercise in comparing the family’s DNA results.
Simply Irresistible: Dimples
If both your parents have dimples odds are you will too, although it’s not a guarantee. Many people are born with dimples that fade over time.
Pull out the photo albums and take a peek at baby pictures of mom, dad, grandparents and other family members. See any dimples? How about mom and dad at school age?
Can you curl your tongue up into a tube? If so, you can thank your genes for that. However, nature loves to break the rules and this one can actually be influenced by your environment: that means you can learn to roll your tongue regardless of if you have the gene. (Unless, of course, you don’t want to).
Practice some tongue rolling skills, and take stock on who can do it and who cannot. Ask friends, teachers and family members and make a tally.
