A focused population profile of Saudi Arabs from Hejaz, their western Arabian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Hejaz is the western Arabian region along the Red Sea, including major cities such as Mecca, Medina, Jeddah, and Taif. It has long been a crossroads for pilgrimage, trade, scholarship, and movement across the Red Sea and wider Islamic world.
Hejazi Arabic is the regional Arabic variety associated with western Saudi Arabia. Because Hejaz includes pilgrimage cities, its population history can be more cosmopolitan than interior Arabian regions such as Najd.
A Saudi Arab Hejaz genetic profile should therefore be read as a western Arabian reference, often still close to Arabian Peninsula groups but potentially shifted by the historic Red Sea and pilgrimage-route context.
In the World Genetics modern G25 comparison, the closest non-self match for Saudi Arab Hejaz is Bedouin Jordan. Other nearby references include Yemeni Arab Al Bayda, Saudi Arab Jizan, Yemeni Arab Ma'rib, and Yemeni Arab Dhamar. This gives the Saudi Arab Hejaz profile its nearest modern genetic context inside the current reference database.

The ancestry model gives a deep component fit, while the closest-match table shows modern similarity. Hejazi Saudi results should be understood in the context of western Arabia and the Red Sea corridor.
The heatmap should emphasize western Arabia and the broader Arabian Peninsula, with possible affinity toward nearby Red Sea and Yemeni references depending on the comparison.
The closest non-self match in this World Genetics comparison is Bedouin Jordan. Other nearby references include Yemeni Arab Al Bayda, Saudi Arab Jizan, Yemeni Arab Ma'rib, and Yemeni Arab Dhamar.
In the current modern G25 reference set, Bedouin Jordan is the closest listed match to the Saudi Arab Hejaz average after removing Saudi Arab Hejaz itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Saudi Arab Hejaz G25 average, giving the closest-match results a geographic view.
