Table 5 Genetic differentiation (F ST ) and Gene flow (N m ) between normal and melanic forms of sympatric and allopatric populations of An. arabiensis captured in different localities in Sudan in 1999–2000 and 2004-2006

From: A genotypically distinct, melanic variant of Anopheles arabiensi s in Sudan is associated with arid environments
