  • Title: Patterns of genetic diversity and differentiation in the tsetse fly Glossina morsitans morsitans Westwood populations in East and southern Africa.
    Author: Ouma JO, Marquez JG, Krafsur ES.
    Journal: Genetica; 2007 Jun; 130(2):139-51. PubMed ID: 16897444.
    Abstract:
    Genetic diversity and differentiation within and among nine G. morsitans morsitans populations from East and southern Africa was assessed by examining variation at seven microsatellite loci and a mitochondrial locus, cytochrome oxidase (COI). Mean COI diversity within populations was 0.63+/-0.33 and 0.81 taken over all populations. Diversities averaged over microsatellite loci were high (mean number of alleles/locus>or=7.4; mean HE>or=65%) in all populations. Diversities averaged across populations were greater in East Africa (mean number of alleles=22+/-2.6; mean he=0.773+/-0.033) than in southern Africa (mean number of alleles=18.7+/-4.0; mean he=0.713+/-0.072). Differentiation among all populations was highly significant (RST=0.25, FST=0.132). Nei's Gij statistics were 0.09 and 0.19 within regions for microsatellites and mitochondria, respectively; between regions, Gij was 0.14 for microsatellites and 0.23 for mitochondria. GST among populations was 0.23 for microsatellite loci and 0.40 for mitochondria. The F, G and R statistics indicate highly restricted gene flow among G. m. morsitans populations separated over geographic scales of 12-917 km.
