Data from 585 chickens and 298 households were recorded for the investigation of adaptability of backyard poultry to rough management and harsh environmental conditions in two geographically distinct sites in Sri Lanka. The molecular investigation using 20 microsatellite markers revealed a high and stable genetic diversity within populations but low genetic differentiation among populations. The management strategies that support this particular genetic structure could be attributed to the constant gene flow through exits from and entries to the flocks of backyard chickens among the villages, and a directional natural selection towards adaptability to local environmental conditions.
