Kerala Y Dna and miscellaneous

[Slayeroid]

Got acess to some Kodava samples a while back and none of them see to be exotic , pretty much identical to Many Bunts , Nairs and Nazranis.Their results seem to have been hyped up based on phenotype.

Pca plot for several Malayali and Tulu  communities .

Hi..do you have the harappa run or the G25 coordinates of these coorgs?..can you post here?

[vishankar]

one more nambudiri sample of mine..i got Y-dNA at 37 markers...R-M 198...broadly this seems to be a common haplogroup in India...part of the R1a group encompassing the mass of eastern europe,India and many arabs and iranians!

Thanks to the family tree dna "discover your haplogroup" endeavor...I am posting some haplogroups( y-dna , 37 MARKERS here).
my only Kurichiya sample- R-SK2153 ..I need more info on this ..is it part of R-M207?

[vishankar]

Here are some I just received-

1)Payyanur Poduval- R-Y6.
2) ernakulam nair( without a known history of nambuthiri forefathers)- L-M27.
3)saliya(kannur)-L-PAGES00116.
4)vaniya( thalassery)- R-Y6.

That is mine from illustrative dna

here is one more ezhava from south kerala settled in kannur- R-Z2124.

Genetic evidence for a single founding population of the Lakshadweep Islands
Lakshadweep is an archipelago of 36 islands located in the Southeastern Arabian Sea. In the absence of a detailed archaeological record, the human settlement timing of this island is vague. Previous genetic studies on haploid DNA makers suggested sex-biased ancestry linked to North and South Indian populations. Maternal ancestry suggested a closer link with the Southern Indian, while paternal ancestry advocated the Northern Indian genetic affinity. Since the haploid markers are more sensitive to genetic drift, which is evident for the Island populations, we have used the biparental high-resolution single-nucleotide polymorphic markers to reconstruct the population history of Lakshadweep Islands.  Using the fine-scaled analyses, we specifically focused on (A) the ancestry components of Lakshadweep Islands populations; (B) their relation with East, West Eurasia and South Asia; © the number of founding lineages and (D) the putative migration from Northern India as the paternal ancestry was closer to the North Indian populations. Our analysis of ancestry components confirmed relatively higher North Indian ancestry among the Lakshadweep population. These populations are closely related to the South Asian populations. We identified mainly a single founding population for these Islands, geographically divided into two sub-clusters. By examining the population’s genetic composition and analysing the gene flow from different source populations, this study contributes to our understanding of Lakshadweep Island’s evolutionary history and population dynamics. These findings shed light on the complex interactions between ethnic groups and their genetic contributions in making the Lakshadweep population.

I think you can get the full paper for free here,

The study also suggests that the populations in mainland India that are genetically closest to the Lakshadweep islanders are seven Scheduled Caste and Scheduled Tribe populations — Dharkar, Dusadh, Harijan, Kanjar, Kurumba, Kol and Velmas. The Velmas and Kurumbas are from south India while the others are native to northern India.

This was interesting , guessing from the closest matches that they should not be really different from Ezhava , Thiyya or Saliya like pops.

yes...unfortunately  recent papers seem to draw weird  conclusions!...I am talking about  the L.Kumar paper on ancestry in south west india...which claims nairs ,thiyyas etc draw ancestry from Jat sikhs and henceforth scythians and huns!!!....bronze age north west Indian populations were probably Iran _N +AASi rich...a common component for many populatiions in the Indian subcontinent...that is my inference from the study....similarly the Lakshadweep populations are historically mainly  derived from mainland  malayalis....and there is a book by sirajudeen which states that they had an upper strata Koyas...derived from nairs and nambuthiris( probably)...and a lower strata from  Thiyyas etc...nairs are characterised by paternal northern indian ancestry (nambuthiris) and maternal south ancestry( M and R HAPLOGROUPS)...and the ezhava ,thiyya saliya....in two fits ,conform to the Velamas+SC/ST mix....nairs too..although in the nair'scase...the mix is north indian SC( dusadh/kanjar/meghawal)+south iindian brahmin....

These papers claiming that Jatts or any other South Asian group descend from Scythians are ridiculous lol, I ran qpadm on the Saka before on the old genarchivist forum and they contained a lot of Mongol_IA type ancestry, which is pretty much non-existent in South Asia.



Also, Meghwals don't work as a substrate population for any South Indian population, since they contain around 25-33% Indo Iranian admixture.

Nairs can also be modelled as a mix of North Indian Brahmins + South Indian mid caste
