Jomon mtDNA

[ButlerKing]

Pure Jomons didn't exist even when Yayoi arrived to Japan. Some Jomon groups were heavily mixed.


All these 3 Jomon groups have M7a, D1, N9b in different percentages with the 2nd group being the purest and most dominant


" In another study, ancient DNA recovered from 16 Jomon skeletons excavated from Funadomari site, Hokkaido, Japan was analyzed to elucidate the genealogy of the early settlers of the Japanese archipelago. Both the control and coding regions of their mitochondrial DNA were analyzed in detail, and 14 mtDNAs could be securely assigned to relevant haplogroups. Haplogroups D1a, M7a, and N9b were observed in these individuals, and N9b was by far the most predominant. The fact that haplogroups N9b and M7a were observed in Hokkaido Jomons bore out the hypothesis that these haplogroups are the (pre-) Jomon contribution to the modern Japanese mtDNA pool.[45] In another study of ancient DNA published by the same authors in 2011, both the control and coding regions of mitochondrial DNA (mtDNA) recovered from Jomon skeletons excavated from the northernmost island of Japan, Hokkaido, were analyzed in detail, and 54 mtDNAs were confidently assigned to relevant haplogroups. Haplogroups N9b, D4h2, G1b, and M7a were observed in these individuals, with N9b being the predominant one. "

N9b

68% in 1st Jomon group
60% in 2nd Jomon group
16% in 3rd Jomon group


M7a

7.9% in 1st Jomon group
36% in 2nd Jomon group
3.5% in 3rd Jomon group


Jomon mtDNA in Japanese and Okinawans ( M7a and N9b )






" Studies published in 2004 and 2007 show the combined frequency of M7a and N9b which are believed by some to be pre-jomon maternal markers to be at least 28% in Okinawans (7/50 M7a1, 6/50 M7a(xM7a1), 1/50 N9b), 17.6% in Ainus (8/51 M7a(xM7a1), 1/51 N9b), and 10% (97/1312 M7a(xM7a1), 1/1312 M7a1, 28/1312 N9b) to 17% (15/100 M7a1, 2/100 M7a(xM7a1)) in mainstream Japanese.

So in Japanese Jomon mtDNA is 10 - 17% on average where as Jomon Y-DNA is 37%
In Okinawans Jomon mtDNA is 28% on average where as Jomon Y-DNA is 56%

The Jomons and Ainu are much more complicated than I though


There was never such as thing as pure blooded Jomon by the time Yayoi (ancestors of Japanese arrived ). Many Jomons were already pure Jomon in phenotype to half Jomon in phenotype. Ainu are quite close to the the original only many of them today have 20% Jomon blood but some are still 60-80%


Jomons racial features are: short broad noses with large nostrils, to long hook noses, with thicker lips and larger mouth, with round eyes. Hair is generally wavy to sometimes straight



Here a facial reconstruction of Jomon, they already existed before the Japanese invaded but this Jomon clearly has strong or noticeable Neo-mongoloid admixture.



Mixed Jomon on the left, Pure Jomon on the right

[ButlerKing]

Jomon female mtDNA might even be much higher in Japanese , Ainu, Okinawans. If Jomon group that interbreeded with Yayoi was more similar to the 3rd Jomon group



Haplogroup N9b, M7a are Jomon mtDNA and if we include D1 together makes up for 77% - 95% in 1st and 2nd ancient Jomon group, however the third ancient group has only 42% Jomon mtDNA, 50% Yayoi mtDNA, 8% unclassified with substantial frequencies of C3 in paternal Y-DNA but only 70% D2



Here is what the Jomons already looked liked when they interbreeded with Yayoi people

It was already a predominately Proto-Mongoloid (Jomon) with Neo-Mongoloid admixture ( Siberian Mongoloid)

Interesting.

[ButlerKing]

Interesting.

It sure is, I though Ainu was 100% pure before mixing with Nivkhs but who would have though that even ancient Jomons (ancestors of Ainu) were already mixed ( despite being more purer than Ainu)

The pure 100% Jomon blood concept never existed at least not when the Yayoi (ancestors of Japanese) have arrived


1862 illustration of Ainu and Nivkhs



Ainu have 12.5% to 25% C3 and 21.6% mtDNA Y which is typical of Nivkhs.


In a study by Tajima et al. (2004), two out of a sample of sixteen (or 12.5%) Ainu men have been found to belong to Haplogroup C-M217, which is the most common Y-chromosome haplogroup among the indigenous populations of Siberia and Mongolia.[47] Hammer et al. (2006) have tested a sample of four Ainu men and have found that one of them belongs to haplogroup C-M217.[49] Some researchers have speculated that this minority of Haplogroup C-M217 carriers among the Ainu may reflect a certain degree of unidirectional genetic influence from the Nivkhs, a traditionally nomadic people of northern Sakhalin and the adjacent mainland, with whom the Ainu have long-standing cultural interactions.[47]

I believe a a Neo-Mongoloid Siberian race similar to Nivkhs have contributed substantial neo-Mongoloid DNA to the Jomons explaining why the 3rd group Jomon have 50% mtDNA A, B, F ect and 30% C3 in Y-DNA

They even live right next the the Ainu today.

GOD WHY IS IT SO CONFUSING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It seems M7a is more common in some Jomon groups than other Jomon group and since Japanese, Ainu, Okinawans have higher mtDNA M7a this means their Jomon DNA contribution must have been similar to Jomon group with this genetic profile.


( 1st bar is obviously Japanese, 2nd bar is Okinawans )

25% M7a
5% N9b
38% D?





I can only have this facial expression

[ButlerKing]

M7a is found in all Jomon, Ainu groups and in every Japanese, Okinawans groups however these types their M7a is 9x higher than N9b.

One Jomon group I've seen had 38% M7a but how do we explain the so much lower frequencies of N9b? could it be genetic drift? or perhaps few Jomon group with higher M7a were more populous than more Jomon groups with N9b but are nowhere as populous ? or could it be they were mainly descent from one Jomon group.

[ButlerKing]

WHAT THE HELL! So now we have Jomon groups who have only 10% M7a but 0% N9b?

Where as haplogroup N9a where descendants from Yayoi?

[Hexachordia]

Why are you so confused? do you expect pure jomons to be self-fertilizing hermaphrodite? , mtdna a b c f n m were originally with jomons and ainus. This is the fact about ugly asian females.

[ButlerKing]

I need a Japanese to help me. Language translator doesn't translate those charts, and there is nothing written underneath it to suggest what those Japanese words means.

I recongnized the word here means Jomon people, but why than they lack mtDNA N9b and have only 6% M7a, or could it be the rest were already Jomon mtDNA themselves. I guess Jomon mtDNA is as high as 30 - 50% in Japanese and Okinawans.



I ask for any friendly Japanese to help me out please. I'm confused and trying to solve the mystery.
