Has there been released test data regarding whether or not there was a y chromosome? That seems to be the question that I have heard, and last that I heard it wasn’t resolved. I know this isn’t a popular opinion on lemmy, but I can understand the question.
I’ve only encountered the use of mulatto once in the wild. My girlfriend my freshman year at college had an adopted brother who was biracial. She used the word mulatto to describe him, but at the time everything she said about him seemed very loving.
