50% Irish, 40% English, 5% French, 5% Scottish
How do you have anything other than binary fractions of ancestry? (like 1/2, 1/4, 3/8, etc) I don't get 40%..
People who don't understand genetics and basic math. You're correct in that the percentages should always be equivalent to fractions with powers of 2 as the denominator.
In high school I had an argument with a guy who said that he was 1/3 (something), 1/3 (something else), and 1/3 (something else). I asked him how that was even possible, and he said that his dad was something and his mom was half this and half that (sorry, I don't remember what they all were). I told him that that would make him 1/2, 1/4, and 1/4. He kept insisting that they were all 1/3's because there were three different heritages and that's how fractions work. I just gave up. Not everyone learns genetics by secondary education, but if you can get to high school and still not understand basic fractions, you shouldn't even pretend to understand genetics.
