It seems like you're open to learning more about genetics (I think...) so I'll share some interesting findings that don't really fit with the popular conception of race.

While we can use 'junk DNA' to classify people somewhat well, that doesn't tell us much about what makes a person a person.

This is not a controversial view - here's a discussion of it for example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1893020/
