At which point SSA becomes ''invisible''?

[Adamastor]

What's the maximum percentage of Sub-Saharan ancestry one can have without showing on phenotype? I'm talking about averages, I know these things can vary from indvidual to individual.

I ask because I have a cousin (his grandfather is my grandfather's brother) and everyone thinks he looks Arab/Iranian/Indian/Moroccan etc (any ''brown Caucasoid'') and I always assumed him to be something like 70% European and 30% Amerindian. But he did a test recently and came out 90% European, 9% SSA and 1% Amerindian. Is his MENA type of phenotype a fruit of his Sub-Saharan influenced genetics or just South European ''exoticness'' (he looks like a cross of Rui Patrício, Fabio Quagliarella and Davide Zappacosta)?

I've seen many Brazilians around 80-90% European and the rest SSA who don't look white.

Multigenerational mixes differ from one-time admixture events. 1/8 SSA may not be visible at all in many cases. Brazilians are very mixed with black blood coming from both sides.

My mother is roughly 7-10% with no visible SSA traits

I agree. I guess for one time mixture events it is 1/8 to 1/16. For multigenerational mixes it can be more complicated.

[GreentheViper]

I’d say roughly 10% and under. Anything above 10% tends to show, even if only minor traits.

[Cumansky]

Depends what is your genetic mix

If you put a SSA admixture in a naturally light person it might show more visible than some hairy swarthyness person

[Abdelnour]

5 percent. Most Gazans are around 8 percent SSA and people think they look more like Egyptians then regular Palestinians.

A very intelligent person told me that an advanced anthropologist can always see something that has at least 2 genetic points.
It may be true. Being an amateur is not the same as dedicating your life to it.

Anything below physics in the modern world called 'science' is whored out to commerical interests. Physics is the king of all sciences in that all sciences must obey its laws. As someone who actually graduate degreed in math and physics, and has had the misfortune of working in the life sciences, I know for a fact that most of what passes itself off as science is simply profit motivated statistical manipulation.

Most scientific studies below physics live and die by their statistical p-value the problem is that scientists are human and if they worked years on a project and they are let down by the numbers they are likely to fudge them to meet their standards so they can get paid to do more research.

Science has been almost completely compromised, if it ever had any honor at all. The medical and life sciences are the very worst offenders. I am not the only one who thinks this. In 2009 the editor of NEJM quit in disgust saying that none of the studies coming out could be trusted.

According to Colin Campbell it is possible to prevent most of the cancers. Health care is 17% of US GDP,.IF a cure for cancer were found, it would literally collapse the economy.

Science has become a religion and a political tool, anyone who believes in it has not examined the evidence.

Science has prostituted itself out and is no longer trustworthy.

For instance, only AncesryDNA has me 1% nigerian and that is because it is an American mormon company and because I have a hiberno-norman name they assume I am 'Irish' and bred with slaves rather than the reverse that I was the Anglo-Norman English aristocracy of Ireland like British statesman Edmund Burke who shares the last name. With sites who don't know my name or who are more objective like dna.land (a Columbia university subsidary), GEDmatch, ,myancestry.com, mytrueancestry.com, lukasz eurogenes k36 analysis, Frenchman Tolan's analysis, and Davidksi's Celtic vs Germanic PCA etc.. etc.. and also the fact that I know that I cluster significantly with a Celto-Germanic gladiator from York England so on and so forth I don't have any African and they instead show at most some oceanian ancestry (very small like 1.5%) which makes sense in the context of the British empire we can say that ancestrydna is probably full of shit and science needs to get its act together and the biggest violators of science are fucking Americans e.g. AncestryDNA and 23andme. Also, that you claim a so called Nazi like scientist can tell it at 2 genetic points is likely bullshit since phenotype is only a small subset of genes compared to genotype.

Basically, if you are not doing physics you are a whore.

1) SSA-North African is Caucasoid different from the Brazilian black who is SSA-Bantu with own skull.
2) In the first miscegenation is totally black due to the dominant SSA genes.
3) In Brazil there is mongoloid skull of amerindian. You can search in Minas Gerais or Rio de Janeiro which is predominant Euro/SSA.

[21993]

It most probably comes from 9% SSA but I should remind that lots of Iranians and Indians have less SSA than most Southern Europeans and French.

[luc2112]

SSA-North African not Bantu skull.

Let's math this out.


One drop of blood is about 50 microliters. There is about 5000 millilitres of blood in the average person's body.

50microL/5000miliL = 0.05mL/5000mL = 0.00001%


0.00001% SSA makes you black.

Maybe, but this guy has two fully European grandparents and his non-fully Euro grandparents have one fully Euro parent and a mixed parent, so I'd not say he's an average multigenerational mixed Brazilian.

Summing up:

His paternal grandfather: 100% European, both parents were from Europe (Northern Italy)
His paternal grandmother: mixed father (likely Portuguese + black) and fully European mother (Portuguese)

His maternal grandfather: European father (Portuguese/Basque) and mixed mother (Portuguese + Black)
His maternal grandmother: 100% European (Portuguese, Spanish, Italian).

I've seen many similar cases here in Brazil. People with recent European ancestry but looking kinda dark with only small amounts of non-white blood. Maybe Southern Europeans are the ones to be blamed for this ''darkness'', who knows.


My mother is roughly 7-10% with no visible SSA traits

That's the problem, this guy I'm talking about isn't SSA or even Quadroon/Mulatto influenced. He looks Arab (and of the non-SSA admixed kind) or something in that vein. My question is if that look is due to some dilluted SSA that cannot be perceived or just normal S. European exoticness.

I disagree, I think North European + SSA generally is easier to dillute than Southern European + SSA. It must be also noted that many Mediterranean European groups have some SSA-related affinity. I've seen Portuguese, Spaniards and Italians scoring SSA blood.

[TheOldNorth]

~20% is the cut off line, and higher and an individual may identify as black, any lower and they might not even know they’re part black

[Tooting Carmen]

It's very random. For example, Ryan Giggs doesn't look part-SSA at all despite his Sierra Leonean grandfather, but his brother very much does.

[Samnium]

Black geneq are so "strong" (in reality it's the fact that they are the farthest group of people genetically speaking) from that they can appear even at low percentage. I do think that the bottom line is 3/4% .

I’m 8.5-10% SSA with no visible SSA traits at all. My dad has double my SSA and his traits are fairly obvious, especially when he was younger, his sisters all show these traits too. It shows clearly even through the rest of his ancestry which is mostly Chinese, French and Indian. I think it varies on a case by case basis

What are the traits?
Dravidian are caucasians for me:
