r/DNAAncestry

i recently used my 23&me data on GEDmatch. i have no native dna shown on my 23&me report and found this interesting to see even if it’s a small amount like it is. i’m just trying to figure out whether this is just noise or actually from a single native ancestor generations back. i’m still very much trying to figure out how to use and understand a lot of the stuff on this site lol

I found out that my Y Haplogroup is R1b, but it confuses me given my ethnic backround. Isn’t Eastern Europe supposed to be R1a? Can someone explain how this is possible?

The Black Death pandemic, combined with the antisemitic climate of 14th-century Europe, led to widespread violence against Jewish communities, including pogroms such as the one in 1348 in Tàrrega (Catalonia, Spain). In the Roquetes necropolis of Tàrrega, six communal graves containing at least sixty-nine individuals, with signs of violence, were dated to the mid-14th century.

It was determined that this was a non-familial mass burial event: no first- or second-degree genetic kinship was found among analyzed individuals, and a significant fraction of the broader burial assemblage exhibits perimortem cranial trauma, indicating significant physical violence they endured prior to death.

The Roquetes individuals show high mitochondrial diversity (haplogroups H, J, K, L, M, R, U), contrasting with the narrow mtDNA spectra documented in medieval Ashkenazi communities at Erfurt (Germany), where strong founder effects and drift operated [20], and at Norwich, where elevated levels of consanguinity could also have influenced the genetic drift [21].

Among the four male victims, the study detected J2 (J2a2a1~*), E (E-CTS9507; E-Y231455), and G (G-PH1944/FT19393) haplogroups. These lineages have deep Neolithic–Bronze Age roots in the Eastern Mediterranean/Levant and adjacent regions and are frequent in Jewish diaspora groups [19,66,77,78]. The recurrence of E1b1b-lineages in medieval Jewish cemeteries (Erfurt, Norwich) and the presence of J and G among present-day Jewish groups further underscore continuity from Levantine–Mediterranean ancestry sources [20,21,78,79,80].

qpAdm identifies two-way models that fit the Roquetes population as a mixture of Canaan (labeled as Israel Middle/Late Bronze Age) and non-Jewish non-Islamic medieval Iberian populations (p = 0.158), with point estimates around ~0.69 for Levantine ancestry and ~0.31 for Iberian medieval ancestry. Among one-way models, only the Erfurt subgroup with Middle Eastern affinity is marginally plausible (p = 0.098), consistent with a Levantine-centered core plus Iberian admixture. Together, these results indicate that the Roquetes victims preserved a distinctively Jewish genetic signature while incorporating local Iberian ancestry.

A few weeks ago ancestralgenome updated the periodical breakdown and mine changed quite a bit. I’m from a coastal city called Misrata.

My great grandfather and I have an aristocratic Japanese phenotype and I've been getting Japanese and Korean results as of late. Choshiu phenotype only found in Japanese aristocrats, mainly samurai. I also have a relative on gedmatch named sengoku, dynasty of choshiu region. And my distance matrix on dnagenics says African Japan 16th century

First Slides of periodical is Global then I did the last one on central euro northwest euro and east euro for comparison. Thoughts?

My mom is a Moroccan Jew. I thought it would be fun to share.

Number 4 from among select few to a late Bronze Megiddo .

Yoruba.DG
Model: Yoruba.DG
Sources: Tanzania_Pemba_600BP 90.7%, Morocco_Iberomaurusian 9.3%
p = 0.163
chisq = 16.7
Status: PASS
This passes, and the Morocco_Iberomaurusian component is supported with Z = 2.90, but the overall fit is only moderate. p = 0.163 is decent.

Gambian.DG
Model: Gambian.DG
Sources: Tanzania_Pemba_600BP 88.3%, Morocco_Iberomaurusian 11.7%
p = 0.579
chisq = 10.4
Status: PASS
This one looks good. The p-value is solid, chisq is reasonable, and the Morocco_Iberomaurusian component has Z = 3.07, so it is meaningfully supported. This is the best of these three.

Kongo.DG
Model: Kongo.DG
Sources: Tanzania_Pemba_600BP 96.2%, Morocco_Iberomaurusian 3.8%
p = 0.161
chisq = 16.7
Status: PASS
This passes, but it is not very strong. The Morocco_Iberomaurusian component is only 3.8% with Z = 0.928, so it is not clearly required.

It should be noted that Tanzania_Pemba_600BP is modeled as 100% Bantu South Africa Ovambo in another study. ( https://www.researchgate.net/figure/Admixture-history-of-ancient-African-populations-A-Overview-of-coexistence-of-distinct_fig3_342135975 )
Mostly Bantu genetically. I tried several other source combinations but couldn’t get any to work as well as this one.

The Taforalt ancestry within West Africans is based on Figure 2 of this study: https://www.biorxiv.org/content/10.1101/423079v1.full

A relatively high amount of Dutch compared to other people I know.
