Are Berbers and Arabs in North Africa genetically different?

Only slightly. Genome-wide studies find that Amazigh and Arabic-speaking Maghrebis share the same deep North African ancestry, with Arabic speakers carrying a modestly larger Middle Eastern component on average. Geography predicts ancestry better than language does, so neighbours of either language are usually closer to each other than to distant communities.

What is the oldest ancestry in the Maghreb?

The Iberomaurusian ancestry of Taforalt, sequenced from individuals about fifteen thousand years old. It was itself a mixture of a Natufian-related Near Eastern stream and a deeply diverged African stream, and it survives as the local foundation in every modern Maghrebi genome, diluted by later additions.

How much sub-Saharan African ancestry do Maghrebis have?

It varies with geography more than with language. Published estimates range from a few percent in parts of Tunisia and northern Morocco to a fifth or more in southern Moroccan and Saharan communities. Most of it entered within the last thousand years through trans-Saharan trade, on top of the much older African component already present at Taforalt.

Are the Guanches related to modern Berbers?

Yes. Genome-wide data from indigenous Canary Islanders show a North African population closest to Late Neolithic Moroccans, settled from the mainland around the start of the first millennium AD. Because they were isolated before the Arab conquests, they are the best available reference for pre-Islamic Berber ancestry, and they carry the same E-M81 paternal and U6 maternal lineages.
