The Ingush are a native ethnic group of the North Caucasus, mostly inhabiting the Russian republic of Ingushetia. They refer to themselves as Ghalghai (galgay). The Ingush are predominantly Sunni Muslims and speak the Ingush language. Despite popular misconceptions, Ingush is not mutually intelligible with Chechen, though they are closely related. The Ingush and Chechen peoples are collectively known as the Vainakh. The Ingush are predominantly Shafi_i Madh'hab of Sunni Islam and there is some Sufi minority present. "The Caucasus populations exhibit, on average, less variability than other populations for the eight Alu insertion poly-morphisms analysed here. The average heterozygosity is less than that for any other region of the world, with the exception of Sahul. Within the Caucasus, Ingushians have much lower levels of variability than any of the other populations.
