Who have more Black African ancestry: Madeiran Portuguese, white Americans, or white South Africans?

[Lucas]

I am full Madeiran and show 1.2% SSA on 23 and me. By the way, if you visit Madeira you will see 100% black Africans, there are few but they are there and after 15 years and 4 trips, I have yet to see any mixed looking Portuguese even in this day and age. So to say 10% of the population being slaves all integrated and mixed is not true and doesn't make mathematical sense either. We have also yet to determine for sure scientifically if sub saharan African is from the Atlantic slave trade. Is is possible that Morisco Portuguese were sent mostly to Madeira?

I agree, I was in Madeira on holidays some time ago and I didn't notice any mulatto or quadroon looking Madeirans.

The Sub-Saharan has been diluted significantly, it will not show in phenotype. But is clearly not from North African input.

[Nico Nobrix]

Because the SSA in Madeira is on their maternal side (mtdna L). The North African input in Iberia is on the paternal side mostly.

My paternal haplogroup is G and maternal is H7...

[Nico Nobrix]

For Portuguese with no haplogroup L, what does that mean when we have sub saharan but not the haplogroup to show it? North Africans do have SSA you know and I do know that genetics are like roulette, your genes can pick up ancestry from a very very long time ago.

Based on the the white South Africans I have met in Australia, which there is a relatively large community of them here, they have 0% SSA ancestry. If they do, they usually identify as mixed race and not as White, and have very recent SSA ancestry. Madeiran Portuguese would be having the most SSA ancestry on average, which is still very little.

Practically all Afrikaners have minor SSA ancestry, but it's not enough to show up in phenotype.

Interesting, has there been any studies on their DNA? It surely must typically be from relatively distant SSA ancestry.

Yes, there's a thread with Afrikaner 23andMe results on this forum.

yemeniantillean is the whitest afrikaner that i know of, hes 200% caucasoid

Are you sure the majority have minor SSA DNA though? There's some who have been in South Africa for only 3 generations for example, I doubt they have mixed.
