This study aimed at reporting the phenotypic and allelic distribution of ABO<\/jats:styled-content> and R<\/jats:styled-content>hesus (R<\/jats:styled-content>h) groups in various ethnolinguistic groups in the C<\/jats:styled-content>ameroonians. We obtained ABO<\/jats:styled-content> and Rhesus blood groups and self\u2010identified ethnicity from 14\u00a0546 C<\/jats:styled-content>ameroonian students. Ethnicity was classified in seven major ethnolinguistic groups: A<\/jats:styled-content>fro\u2010A<\/jats:styled-content>siatic, N<\/jats:styled-content>ilo\u2010S<\/jats:styled-content>aharan, N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/W<\/jats:styled-content>est A<\/jats:styled-content>tlantic, N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/A<\/jats:styled-content>damawa\u2010U<\/jats:styled-content>bangui, N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/B<\/jats:styled-content>enue\u2010C<\/jats:styled-content>ongo\/B<\/jats:styled-content>antu\/G<\/jats:styled-content>rassfield, N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/B<\/jats:styled-content>enue\u2010C<\/jats:styled-content>ongo\/B<\/jats:styled-content>antu\/M<\/jats:styled-content>bam and N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/B<\/jats:styled-content>enue\u2010C<\/jats:styled-content>ongo\/B<\/jats:styled-content>antu\/E<\/jats:styled-content>quatorial. ABO<\/jats:styled-content> allelic frequencies were determined using the B<\/jats:styled-content>ernstein method. Differences in phenotypic distribution of blood groups were assessed using the chi\u2010square test; a P<\/jats:italic> value <0.05 being considered as statistically significant. The frequencies of the antigens of blood groups O, A, B and AB<\/jats:styled-content> were 48.62%, 25.07%, 21.86% and 4.45%, respectively. Rhesus\u2010positive was 96.32%. The allelic frequencies of O, A and B genes were 0.6978, 0.1605 and 0.1416, respectively. Phenotypic frequencies of the blood groups in the general study population and in the different ethnolinguistic groups were in agreement with H<\/jats:styled-content>ardy\u2013W<\/jats:styled-content>einberg equilibrium expectations (P\u00a0<\/jats:italic>>\u00a00.05). The frequencies of O, A, and B blood phenotypes were significantly lower, respectively, in the N<\/jats:styled-content>ilo\u2010S<\/jats:styled-content>aharan group (P<\/jats:italic>\u00a0=\u00a00.009), the N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/B<\/jats:styled-content>enue\u2010C<\/jats:styled-content>ongo\/B<\/jats:styled-content>antu groups (P<\/jats:italic>\u00a0=\u00a00.021) and the N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/W<\/jats:styled-content>est\u2010A<\/jats:styled-content>tlantic group. AB<\/jats:styled-content> blood group was most frequent in the N<\/jats:styled-content>iger\u2010K<\/jats:styled-content>ordofanian\/A<\/jats:styled-content>damawa\u2010U<\/jats:styled-content>bangui group (P<\/jats:italic>\u00a0=\u00a00.024). Our study provides the first data on ethnic distribution of ABO<\/jats:styled-content> and Rhesus blood groups in the C<\/jats:styled-content>ameroonian population and suggests that its general profile is similar to those of several sub\u2010S<\/jats:styled-content>aharan A<\/jats:styled-content>frican populations. We found some significant differences in phenotypic distribution amongst major ethnolinguistic groups.
