Frequencies of COI and Tpi strain marker configurations in Africa compared to pooled data from the Western Hemisphere. Configurations are categorized as Concordant (COI-CS TpiC, COI-RS TpiR), Discordant (COI-CS TpiR, COI-RS TpiC), and Heterozygous (COI-CS TpiH, COI-RS TpiH). Number of specimens is indicated above columns. Mean frequencies of the Discordant configurations from Togo and SĂ£o TomĂ© and PrĂncipe collections were compared with that from the rest of Africa by two-tailed t-test analysis.
