Technically she is "right" assuming that "Black Blood" means DNA closest to the modern-day African American, and "how white the color of your skin" means your current DNA.I had a black female college professor yell at the class…… “No matter how white the color of your skin is, you have Black Blood in your genes from your ancestors. “
I’m like OK…..
Others in class had a very good laugh.
I took this class for an easy A and raise my GPA.
Based on the common practice of using DNA deviation to determine where a certain species originally came from, the one closest to the origin has the most diverse gene pool and the least diverse one has been drifted away and breed internally among the migrants instead of with the more diverse original gene pool. This is used to determine whether a bird, a cat, a canine, etc were originally from one place or another and which way they migrated.
If you use the same way to look at human gene pool, that black female college professor is not wrong entirely. She may not be accurate but she was not wrong.
