The legendary Mongol emperor, Genghis khan was born in 1162 near the Lake Baikal. At the age of 9 his father was poisoned by another clan and one of the rival families (Taychiut family) took the power of the Borjigin clan.It is said that this family abandoned the widow and her children which lead them to extreme poverty. Oneday Temujin (Genghis Khan) was captured by Taychiut but he escaped and gathered supporters. Once he became the head of his clan he then stratergically unified Mongolia and extended his empire across Asia to Adriatic sea.
Dr. Chris Tyler Smith discovered that 8% of the men across 16 different ethnic populations across Asia shares a common Y chromosome pattern.The explanation they came up with was that the original possessor has a social advantage over other Y chromosome possessors. Therefore the men in this lineage had increased reproductivity while non related males were eliminated. Upon further investigations they found out the most recent common ancestor lived around 1000 years ago and geographical spread of the possessors almost perfectly matched Genghis Khans empire.To further prove this theory, documents from that era states one of his sons had 40 sons and one of his grandsons had 22 acknowledged sons and there has been more illegitimate sons as well.
However a team of Russian scientists discovered that Genghis Khan has not left his genetic trace in Russia even though Genghis Khans empire controlled Eastern Russia for two and a half centuries.
Since Y chromosome is directly passed down from father to son it is the most convenient way of tracking the paternal lineage. However since there is no Y chromosome equivalent for females, the number of females associated to Genghis Khans clan is still unknown.
