Yes but like arabs, north africans tend to mix culture with genetics and that's wrong you can't only focus on your paternal haplogroup because this only represents one member of your lineage what about the other thousands ? If you want to know who you are genetically then you have to take everything into account. Also there were more black slaves that were imported in North africa than arabs. Arabs were still a small group that got absorbed by the berber mass that's why today it's impossible to find a maghrebi with more than 40% arab ancestry except in eastern libya
