ancestry; some of the most notable ones are Aamir Khan, Shahrukh Khan, Salman Khan, Feroz Khan, Madhubala, Kader Khan, Saif Ali Khan, Soha Ali Khan, Sara Ali Khan, and Zarine Khan. In addition, one of India's former presidents, Zakir Hussain, belonged to the Afridi tribe. Mohammad Yunus, India's former ambassador to Algeria and advisor to Indira Gandhi, is of Pashtun origin and related to the legendary Bacha Khan. In the late 1990s, Pashtuns were the primary ethnic group in the ruling regime i.e Islamic Emirate of Afghanistan (Taliban regime). The Northern Alliance that was fighting against the Taliban also included a number of Pashtuns. Among them were Abdullah Abdullah, Abdul Qadir and his brother Abdul Haq, Abdul Rasul Sayyaf, Asadullah Khalid, Hamid Karzai and Gul Agha Sherzai. The Taliban regime was ousted in late 2001 during the US-led War in Afghanistan and replaced by the Karzai administration. This was followed by the Ghani administration and the reconquest of Afghanistan by the Taliban (Islamic Emirate of Afghanistan). The long wars in Afghanistan have led to Pashtuns gaining a reputation for being exceptional fighters. Some activists and intellectuals are trying to rebuild Pashtun intellectualism and its pre-war culture. Genetics According to a study from 2012 called "Afghanistan from a Y-chromosome perspective", the study from a sample size of 190 showed R1a1a-M198 to be the most dominant haplogroup in Pashtuns at 67.4%. In the north, it peaks at 50% while in the south, it peaks at 65.8%. R1a-Z2125 occurs at a frequency of 40% in Pashtuns from Northern Afghanistan. This subclade is also predominantly present among Tajik, Turkmen, Uzbek, and Bashkir ethnic groups, as well as in some populations in the Caucasus and Iran. Haplogroup G-M201 reaches 14.7% in Afghan Pashtuns and is the second most frequent haplogroup in Pashtuns from southern Afghanistan. It is virtually absent from all other Afghan populations. This haplogroup is reported at high frequencies in the Caucasus and is thought to be associated with the Neolithic expansion throughout the region. Haplogroup L-M20 exhibits substantial disparity in its distribution on either side of the Hindu Kush range, with 25% of Pashtuns from northern Afghanistan belonging to this lineage, compared with only 4.8% of males from the south. Paragroup L3*-M357 accounts for the majority of L-M20 chromosomes among Afghan Pashtuns in both the north and south. According to a Mitochondrial DNA analysis of four ethnic groups of Afghanistan, the majority
