Hutu reify the biological distinctions, generating a taller elite and a shorter underclass, but with 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). Hutus speak Rwanda-Rundi as their native tongue, which is a member of the Bantu subgroup of the Niger–Congo language
Hotel Rwanda President Juvénal Habyarimana, a Hutu, was shot down. Following that incident, the genocide began. Hutu extremists belonging to the Interahamwe militia launched plans to destroy the entire Tutsi civilian population. Tutsi and people suspected of being Tutsi were killed in their homes and as they tried to flee the country. It is estimated that some 200,000 people participated in the perpetration of the Rwandan genocide. Hotelier Paul Rusesabagina of the Belgian owned luxury Hôtel des Mille Collines, used his power and influence to personally save both Tutsi and Hutu refugees. Rusesabagina regularly bribed Rwandan Hutu soldiers and kept militias outside
