I can see two possible special cases that might be worth looking at: when admixture is in the range of 50-60 percent white there’s a possibility that one parent is white and that parent is the breadwinner and may have a greater educational attainment than the black parent; and when admixture is zero, i.e. 100 percent African ancestry, both parents may be recent self-selected immigrants with higher than average income and educational attainment. It be interesting to see what happens to the analysis when these two cases are removed from consideration.
Could it be as simple as black parents don't know that they have to teach their children to read, or that they don't know the secret of "Cat In The Hat" and "Green Eggs and Ham" teaching your kids the 200 words you need to learn to read, to learn to read?
This would show up as shared environment, but usually shared environment is too small to be able to account for gaps. In this case, of course, since it is about parental education and income and not child's intelligence, it's not strictly related to this study.
We could understand this if you wrote it in English, instead of "intellectual I-am-smart speak".

I don't get the comparison. Aren't social race and genetic race in a given individual almost always identical?
Almost but not entirely, thus allowing one to check which one predicts stuff.
