The Ottomans never took armenians as janissaries, the janissaries were all from the balkan (slavs). The immigration of Turks from central-asia started as early as 1020 and continued till 1800. The first wave of Turks came to anatolia in large groups (some 1 million) after the battle of malazgirt in 1071. It is estimated that some 5 million Turks have immigrated to anatolia. Very few Turks have armenian or greek genes, my fathers ancestors came to anatolia from iran in the early 1800's and my mothers family are Tatars from russia. To claim that armenians were somewhat influential in the ottoman empire is one of the armenian myths. They were nothing but troublemakers and terrorists.

ps: the atomic energy in armenia is thanks to russian technology
