is socially constructed. Yes, ancestry and the way one's genetic traits present to the world are absolutely biological. However, the way society interprets those items and treats people is constructed by the society itself. Also, one's ancestry and physical attributes are not something that you feel emotionally without the context of how you're treated in society as a result of those traits. So, "feeling" black, or any race really, does not exist without social context. I get the difference between race and ethnicity, but race as a feeling exists purely as a social construct.
