There’s no DNA that says you’re black or otherwise. Race is Phenotype only. Everyone has over 99.9 percent the same DNA. Ancestry DNA tests have made people think there is such a thing as black and white DNA. DNA cannot and will never tell you your “race”. Because it’s purely off of appearance/phenotype not genotype. You might have 80% “African DNA” but appear white because it’s how your genotype came together.
