Genetic distance between Iranians and Saudis

[Mamluk]

I didn't dig up the source for samples (who may NOT have been good enough) but one simple drawback is that Marathi, Gujarati has been listed without delineating the caste groups as in the case of Pakistani Gujar, for example take Marathi Brahmins

MarathA are a caste themselves.

As for Gujarati, it's mixed caste, including both upper and lower castes, and a lot of them are Patels.

The Pathan, Balouch and North Western Nomadic tribes of Pakistan look identical to Iranians. The y make up nearly 40% of Pakistan's population. I know because I visited these regions in December just gone (2019).

You do know that the area that is now modern day Pakistan and Afghanistan were once all part of the Persian and Safivid empire for over 2000 years?

Of course. Pakistanis share cultural and genetic similarities with Iranians. Particularly Iranians in the southeastern regions of Iran like Baluch people. Has anybody denied that?

More like almost equidistant between French and Saudis. Saudis have more input from a people known as Natufians who lived in the Levant thousands of years ago.

They give you perspective, that some people lack.

Yeah. However it is not clear what distance function they are using though. Apparently there are several distance functions to measure genetic diversity. And some of them are not distance functions mathematically speaking.

Arabs (except the ones from Yemen and Oman) are lighter than us

Skin colour is most closely related to the UV radiations that population receives, of course recent migrations excluded(by recent I mean recent enough to evolve again).

In 1978, NASA launched the Total Ozone Mapping Spectrometer. In 1998, anthropologist Nina Jablonski and her husband George Chaplin collected spectrometer data to measure UV radiation levels around the world and compared it to published information on the skin color of indigenous populations of more 50 countries. The results showed a very high correlation between UV radiation and skin color; the weaker the sunlight was in a geographic region, the lighter the indigenous people’s skin was. Jablonski went on to prove that people living above the latitudes of 50 degrees have the highest chance of developing vitamin D deficiency. "This was one of the last barriers in the history of human settlement," Jablonski states. "Only after humans learned fishing, and therefore had access to food rich in vitamin D, could they settle regions of high latitude." People living far from the equator developed light skin to produce adequate amounts of vitamin D during winter with low levels of UV radiation. Genetic studies suggest that light-skinned humans have been selected for multiple times.[23][24][25]

Yeah, missed that.

Don't bring your Indocentric caste obsession into every topic.

As a Pakistani, I can tell you most of us are dark. Arabs (except the ones from Yemen and Oman) are lighter than us by a shade or two. Not that I think there is anything to be proud of in being lighter skinned.

Let's agree to disagree sir. I think this brave lady who threatened Modi with serpents also disagrees

Damn What a Beauty.

The topic is not about phenotype. Phenotype stuff, like skin color or hair texture, are decided buy a very few SNPs (or mutations), among hundreds of thousands that determine other things.

Theoretically two person could be almost genetically identical but still look quite different.

There's this video about a Levantine girl with blonde hair and blue eyes whose test shows she is genetically no different from other Levantines. Goes to show phenotype can be confusing and phenotype based observation are not reliable to judge genetic distance.

Having said that if you have an interest in understanding skin color variations then you can check this out, this map is pretty accurate: https://upload.wikimedia.org/wikipe...abeled_Renatto_Luschan_Skin_color_map.svg.png

Is not this thing half a century old??

The von Luschan scale was used extensively throughout the first half of the 20th century in race studies and anthropometry. However, the results were inconsistent: in many instances, different investigators would give different readings of the same person. The von Luschan scale was largely abandoned by the early 1950s, replaced with methods utilizing reflectance spectrophotometry.

Who is this woman and why have I never seen her before? I think this is Babra Sharif.

If you want to see a true Pakistani beauty, see Iman Ali.

Very pretty. She looks Southern Iranian too.

You don't think they will all be consistent?

 

[Crusher]

Maybe. Phenotype and genotype are different things.

Genotype is mostly the result of natural selection, Phenotype is often the result of natural as well as sexual selection (based on attractiveness).

Better than anything else out there. Maybe you can find us something more comprehensive and accurate?

Also environment/nature. Andamanese are short (height is phenotype) because of "island effect".

Environment related adaptation is included in the natural selection, other factors could include genetic resistance against diseases etc. Current covid-19 pandemic is applying a natural selection on individuals, those who will survive through it will pass on their genes, those who will die out will be removed from the gene pool.
