Table 2 Hierarchical AMOVA results of Cross River, Cameroonian and Ghanaian groups at various molecular levels.

From: Little genetic differentiation as assessed by uniparental markers in the presence of substantial language variation in peoples of the Cross River region of Nigeria

 

Cross River region (n = 24)

Cameroonian NWP (n = 3)

Ghana (n = 5)

Ibibio (n = 11)

Cross River pooled groups of language speakers (n = 6)

Cross River clans grouped by language (n = 6,24)

Cross River clans grouped by language with 2 Igbo populations (n = 6,26)

Cross River region + Ghana+ Cameroonian NWP (n = 3,32)
