Genetics or Archeogenetics or Quasi-archeaogentics like that of Reich et al, is not about ‘similarity of phenotypes’ or even ‘lineage’.
Please don't mind it but, If you really really, went to read Reich and Moorjani for that reason, you probably deserve a role in Mungeri Lal Ke Haseen Sapne more than anything else.
1) if you have read about Mendelian inheritance and then read these genetic studies you will realize that even recessive genes are inherited and are part of lineage because even these can at times make their appearance felt
2) Y chromosome based studies ignore your Nana ji which could also be a part of your dominant appearance (~25% of appearances). And remember there are as many Nana ji(s) in any given lineage as there are individuals.
3) X chromosome based studies completely ignore your Dadi ji (~25% of appearances). Same logic as #2 point above.
4) Appearnces are mostly likely not even resident on your Y or even the last residual sex-determining X chromosome. These are mostly about sex determination and only crazy people will claim that they are a male/female because they belong to a certain ‘lineage’. Ghanta. And since there are 23 pairs of chromosomes so these quasi-archeaogenetic studies by Reich etc have about 1/23 relevance to your lineage. Combined with point #2 an #3 you can see your own lineage quite well, I guess, by now.
5) Almost all parameters of appearances are polygenic in nature ie. have several different genetic loci controlling it. Most of them not even located on the last XX and XY pair. Combined with all above points you can guess how you look has how much relevance to where your ‘ancestors’ came from.
6) Appearances linking to ‘lineages’ or ‘ancestors’ as stated by these quasi-archeaogenetic studies by Reich etc is horse manure also because there is no fucking way that all the appearances related genes are going to be falling in place as dominant genes or expressive recessive pairs,
in lock step with each other. Your origin or invasions do not determine why your sharp nose goes with white skin and your rounded nose goes with yellow skin and your mixed sharp/round nose goes with black skin. There is a different mechanics for that to happen and origins/invasions/cultural exhanges is not that. Genes have an probability based inheritance pattern. So your white/black skin gene may or may not have any relation with your sharp/round nose gene.
All genetic pairs on paired chromosomes that in their polygenic nature, determine appearance etc, are going to have an equally-likely basis of expression. So admixture does imply that all the polygenes that determine your looks will be randomly distributed.
7) Ancestors also does not imply ‘origins’ because ancestors imply multiple origins. That is why the hopelessly admixed populations of current India constitute a different and identifiable genetic pool far away from the European and/or Far Eastern Genetic pool. Basically all Indians except some very small trace quantity groups are more close to each other than they are to outsiders – sharp/round noses notwithstanding.
8) Similarity of appearances also does not imply ‘cultural’ exchange or even the exchange of genetic material or even invasions/migrations, since what applies on the Western front of India should logically also apply on the eastern front or southern or northern front of India. How many migrations/invasions/cultural exchanges do you want to postulate.
I think I will stop. This is Mul-maas ka mahina and 8 is a good number for this month.
Sorry if I made you feel less important and destroyed your entitlement victor/victim syndrome. Really sorry about that. I am feeling sorry since yesterday. Since when I did some Mazak-udao of that Chinese member. Sorry Bhagwan ji.
Ideally the researchers working on these quasi-archeaogenetic studies like Reich, Moorjani etc should not have mentioned cultural idioms like lineage and ancestors or invasions or exchanges etc. But the mention should not be disheartening either, because these researchers studying these genetics actually started out on the framework of AIT/AMT and today they have successfully made a self-correction in their understandings based on the evidence they themselves sought out and chased down.
For people who think why their sharp noses bears resemblences to Europeans and for people who are upset that theirs does not, my advise is you may try to read early papers on such genetic studies (96/98 period). Researchers used to talk about nebulous ideas like ‘Pre-caucasoid’. These were not defined or defined in nebulous terms like the ‘general caucasoidness of the mass of the Indian populations’
. WTFH – general caucasoidness, what the hell that means. I guess such ideas were in formative stages and I personally suspect that this will ultimately turn out to be true because after all Indians are the fathers and mothers of the rest of you guys outside of India
. Europeans basically owe their sharp noses to Punjabis while the Chinese probably owe their strange eyes to our north-eastern populations. These European and Far eastern looks, being only the highly specialized forms of relatively well admixed Indian genetic material. When I say India please think in terms of Akand Bharat and not restrict yourself to the India starting on 1947.
Remember the M lady and the N lady came into India together. Logically follows that they came into India alongwith their husbands and all the offsprings admixed well.
