Tutsi little relation to the gene pools that had existed a few centuries ago. The social categories are thus real, but there is little if any detectable genetic differentiation between Hutu and Tutsi. Tishkoff et al. (2009) found their mixed Hutu and Tutsi samples from Rwanda to be predominately of Bantu origin, with minor gene flow from Afro-Asiatic communities (17.7% Afro-Asiatic genes found in the mixed Hutu/Tutsi population). Their average height is 5 feet 9 inches, although individuals have been recorded as being taller than 7 feet. Prior to the arrival of colonists, Rwanda had been ruled by a Tutsi-dominated monarchy
Sainte-Famille Church genocide of 1994 thousands of Tutsi and Hutu took refuge in the church and many were massacred, following the death of President Juvénal Habyarimana. Witnesses said that the priest in charge of the church, Father Wenceslas Munyeshyaka, armed himself and helped Hutu militias take people from the church to be killed. Munyeshyaka was responsible for many of the killings, agreeing to "let the militia pick off those they wanted every now and then." Wenceslas Munyeshyaka hated the Tutsis and called them the "inyenzis". Following this incident and similar ones in other churches, many of the Rwandan people converted to Islam.
