First of all, learn some bloody manners. And learn proper genetics while you're at it.
Secondly, you clearly have no idea what you're blabbering about.
Haplogroup R1a originated somewhere near present-day Iran, according to the latest research:

Furthermore, the Brahmins of West Bengal (India) have the highest frequency of haplogroup R1a in the World:

As for Turkey, haplogroup R1a has a frequency of only 7.5%, which is a little higher than in Iraq and Iran:

On average, Eurasian population clusters that are farthest from the Middle East have a greater frequency of either haplogroup R1a or R1b, except for those in the Far East:

As for haplogroup J2, it has high frequencies among all population clusters than can trace their ancestral roots to the populations that migrated out of the northern areas of the Fertile Crescent.
Finally, the people of Turkey have very little to do with the original Turkic tribes of Siberia.
Take a look at this autosomal DNA chart:
The modern day Turks are predominantly descendants of ancient population clusters that inhabited Anatolia and Asia Minor. Genetically speaking, the Turks have more affinity to the peoples of their immediate neighborhood (e.g. the Arabs, Iranians and Greeks) than they do the pure Turkic peoples of Siberia.
Here's another link for you to look at:

^^According to the above link, the Turks are closest to the following peoples:
1. Greeks (11.1%)
2. Armenians (9.9%)
3. Iranians (8.5%)
4. Georgians (7.4%)
5. West Sicilians (7.0%)
6. Cypriots (6.2%)
7. South Italians (6.1%)
That's real science for you. Hopefully it doesn't make you feel uncomfortable lol.
