Where did your genetic ancestors come from?

“Let’s imagine that the individual is you. The maternal genome (the copy from your mum, note correct spelling on mum) is shown on top, and the paternal genome on the bottom. I paint each chromosome with a colour indicating where an individual’s genetic material has been copied from. …Going another generation back see how this means that you have inherited the left part of chromosome 21 from your maternal grandma, and the right half of chromosome from your maternal grandfather.
