DNA Inheritance in Pictures

One of the speakers at FGS 2013 caught my attention through a very elaborate series of drawings demonstrating DNA inheritance. Debbie Parker Wayne has an interesting blog where she discusses DNA, along with other genealogical topics.

I recently shared Debbie's concept with a friend, but I used scrapbook paper, since we were cropping together that day. She gave me these POPS to use from the Club Scrap Simply Beautiful kit (and remix).

Let me introduce you to a lovely couple: Mr Brown and Miss Rose.

They passed bits and pieces of their DNA to their child.

Here's another couple: Mr Green and Miss Vines.

And here's their child.

The two children in turn, marry and have a child of their own. The child inherits bits of DNA from each parent (and grandparent). It's not an exact 25 percent from each grandparent, but rather, random inheritance.

In fact even full siblings will inherit different DNA from each other, which leads to the differences we see within families.

Of course, using these random strips of paper DNA, we find we have a Simply Beautiful grandchild -- I mean card front -- like none other in the world.
