There aren't any "pure races". There aren't even any "races", and I will convey this by quoting a User from another forum.

"Purity" makes sense in metallurgy, but not from a genetic standpoint. When you're dealing with metals, you can analyze them and break down components into specific minerals. You can assay any metal and say it's 57% copper, 32% zinc, etc. because there is an unchanging scientific definition of what copper is, based on its atomic structure, properties, etc. Any two people who know what they are doing will be able to agree on the chemical composition within a very low range of tolerance.

Ethnic groups are not made up of minerals: they're made up of actual people, whose ancestors themselves belonged to various ethnic groups in varying proportions. You can never break down an ethnicity into scientifically agreed-on and stable components the way you can minerals.

Aftermarket projects may give you a "component" score. But these are not "components" in the sense that unalloyed minerals in an alloy are. There never was a single ethnic group that was, say, 100% "West European" by these analyses' definitions.
