NRY diversity, it was determined that the Y-DNA haplogroups F and J2 such as haplogroup J1 are carried at high frequency among the Iranian Arabs, accounting for more than half of Iranian Arab haplogroups. The high ratio of haplogroup F genetically relates Iranian Arabs to Eastern Mediterraneans and the people of the Barbary Coast. An elevated frequency of haplogroup J-M172 is typical of Near Eastern people and reflective of the genetic legacy of early agriculturalists in the Neolithic Near East c. 8000–4000 BCE. Haplogroup R1a1, and R1, typical of Indo-Iranian groups, occurred in more than 11 percent of the sample and haplogroup G was present in more than 5 percent. Haplogroup J1-M267 reaches 33.4% in samples from Khuzestan, higher than in other parts of Iran. It also reaches a frequency of 31.6% in Khuzestani Arabs. Regional groups Khuzestan Most Iranian Arabs in Khuzestan Province speak Arabic and Persian. The Arabic spoken in the province is Khuzestani Arabic, a mixture of Gulf Arabic and South Mesopotamian Arabic. Hamid Ahmadi noted that the Arabs of Khuzestan Province are direct descendants of the ancient population of the area, having adopted the Arabic language and identity with the spread of Islam, although there are numerous immigrant Arab tribes of Khuzestan with origins from the Arabian Peninsula, such as the Banu Ka'b at Dawraq, the later Fallāhīya and present-day Shadegan, the Musha'sha' at Hoveyzeh, Banu Tamim, and more from southern Iraq. The Bani Turuf tribe is settled in the Dasht e Azadegan (formerly Dasht-e Mīshān) around the town of Hūzagān (formerly Hoveyzeh), and consists of seven tribes, the Sovārī, Marzaā, Shorfa, Banī Sāleh, Marvān, Qāṭeʿ, and Sayyed Nemat. North of the lands of the ʿAnāfeja of the Āl Katīr, in the area called Mīānāb, between the Kārūn and Karkheh Rivers, dwell several Arab tribes, of which the best known are the Kaab (probably an offshoot of the Banī Kaʿb of southern Khuzestan), the ʿAbd al khānī, the Mazraa, the Al Bū Rāwīya, and the Sādāt. These tribes gradually immigrated into Iran during and after the early years of the Qajar period. Culture of Iranian Arabs in Khuzestan Strong blood relation which is one of the peculiarities of Arab society, results in cooperation between Arabs in hardships as well as the intensification of internecines between tribes. Iranian Arabs are well known for hospitality too. Iranian Arab Women's costumes Women's scarves have various types including Aba that
