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

Shared, she mentioned one of her grandparents was mixed Senegalese Fulani + Nigerian

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
