Ingush Genetics

"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. The Ingushians also showed unusual patterns of mtDNA variation when compared with other Caucasus populations (Nasidze and Stoneking, submitted), which indicates that some feature of the Ingushian population history, or of this particular sample of Ingushians, must be responsible for their different patterns of genetic variation at both mtDNA and the Alu insertion loci."

According to one test by Nasidze in 2003 (analyzed further in 2004), the Y-chromosome structure of the Ingush greatly resembled that of neighboring Caucasian populations (especially Chechens, their linguistic and cultural brethren)

There has been only one notable study on the Ingush Y-chromosome. These following statistics should not be regarded as final, as Nasidze's test had a notably low sample data for the Ingush. However, they do give an idea of the main haplogroups of the Ingush.

• J2- 89% of Ingush have the highest reported frequency of J2 which is associated with the Fertile Crescent
• F*- (27% of Ingush) This haplogroup was called "F*" by Nasidze. It may have actually been any haplogroup under F that was not under G, I, J2, or K; however, it is probably consists of haplotypes that are either under J1 (typical of the region, with very high frequencies in parts of Dagestan, as well as Arabia, albeit in a different subclade) or F3.
• G- (27% of Ingush) Typical of the Middle East, the Mediterranean and the Caucasus. The highest values were found among Georgians, Circassians and Ossetes. There was a noticeable difference in G between Ingush and Chechens (in J2 and F*, Ingush and Chechens have similar levels), possibly attributable to low samples that were all from the same town.

In the X-chromosome, or mtDNA, the Ingush formed a more clearly distinct population, with distance from other populations. The closest in an analysis by Nasidze were Chechens, Kabardins and Adyghe (Circassians), but these were all much closer to other populations than they were to the Ingush.
