Recently, someone asked me a question about DNA results.

I explained how DNA is inherited – not everyone gets the same pieces as their siblings.

My maternal grandparents shared their DNA with their children (three children) – each child received different “pieces” of DNA from their parents – each received half of their DNA from each parent, but different “pieces” made up that half.  I have been contacted by people whose DNA matches mine, but does not match that of my first cousin – the first cousin is the child of my mother’s sibling. Apparently, my mother’s sibling received different pieces than she did!
