Table 6. Genetic distance among the IC population in Rwanda.

Populations	North West	Central North	Central South	Exotic chicken	East
Central North	0.029
Central South	0.094	0.077
Exotic chicken	0.199	0.213	0.231
East	0.112	0.097	0.117	0.196
South West	0.104	0.092	0.048	0.118	0.125

The extent of genetic distinction among the population with regard to allele frequencies (F_ST) and gene flow (Nm) are presented in Table 7. The results revealed a low genetic differentiation and a high gene flow between CN and NW, and likewise between SW and CS. A relatively high gene differentiation, however, was found between the E population and other populations.
