I've seen pictures from DNA testing companies showing their customers the percent heritage. Like 10% African, 30% Northern European, 60% Asian, etc. those are obviously made up numbers. but the website below has more extensive discussion of how they do it.

it has some cM relations to the percent, but it's not very clear. Can anyone explain it like i'm 5, or is that too much to ask?
