Table 4 Partition of genetic variation between the Sudanese populations (using analysis of molecular variance) based on linguistic or geographic classification.

From: Genetic variation and population structure of Sudanese populations as indicated by 15 Identifiler sequence-tagged repeat (STR) loci

Grouping criteria (n) Groups Variance (%)
   Within populations Between populations, within groups Between groups
Linguistic groups,a (2) Afro-Asiatic, Nilo-Saharan 99.07 0.73 0.21
Geographic groups, (5) Central, Northern, Eastern, Western and Southernb 98.99 0.49 0.52
  1. For all F-statistics, p < 0.01
  2. aSee Figure 1 and Table 1 for the geographic and linguistic classification of populations.
  3. bThe Nuba population was excluded because the group included individuals speaking different languages belonging to the Niger-Congo and Nilo-Saharan linguistic families.
