She has two black grandparents. Her father is a light skin black man from New Jersey with two light skin black parents.
I've seen pictures of her two siblings, they look like your typical light skin black people or biracial people.
You're missing the point trying to correct ppl about her DNA.
I understand genetics. My family has a heavy Asian influence on my Mom's side. My great-grandmother looked straight up like an old Asian lady (RIP).
You wouldn't know looking at my Mom (Who had two light skin parents) or me--both of us are brown like Kobe or Brandy.
The issue is trying to connect this to some larger "Black Renaissance" in the Winter Olympics.
