I want to know the answer to the following question:
What do some people contend racial categories are obviously correlated with?
All the background I'm provided with is that "Nonetheless, some scholars argue that racial categories obviously correlate with biological traits (e.g. phenotype) to some degree, and that certain genetic markers have varying frequencies among human populations, some of which correspond more or less to traditional racial groupings.". Is that enough to answer the question?
Answer: yes
