Genetics
In terms of ancestry, the majority of Gujaratis share identical genes with the rest of the northern Indian populations, but show a significant relationship with West Asia.
A 2004 Stanford study conducted with a wide sampling from India, found that over 33% of genetic markers in Gujarat were partially of West Eurasian origin, the second highest amongst the sampled group of South Asians with Punjabis at 42%, and Kashmiris at 30%.
Haplogroup U7 is found in Iran, the Near East, Afghanistan, India, and Pakistan; with extremely low frequencies in neighboring countries Turkmenistan, Kazakhstan, Uzbekistan, and Iraq. Its frequency peaks at over 12% in Gujarat, 9% in Iran, 9% in Punjab, 6% in Pakistan and 6% in Afghanistan. Elsewhere in India, its frequency is very low (0.00% to 0.90%). Outside of the Near East, Iran, Afghanistan, Pakistan, and the Northwestern Indian states, Haplogroup U7 is non-existent. Expansion times and haplotype diversities for the Indian and Near and Middle Eastern U7 mtDNAs are strikingly similar. The possible homeland of this haplogroup likely spans the coverage of Iran to Western India. From there its frequency declines steeply both to the east and to the west. Its equally high frequency as well as diversity in Gujarat favors a scenario whereby U7 has been introduced by the coastal Gujarat to areas of Iran.
Some preliminary conclusions from these varying tests support some of the highest degrees of Indian mtDNAs found in Western Asia, with a particular close relationship between Iran and Gujarat, supporting a theory of trade contact and migrations out of Gujarat into West Asia.
