From: Population-specific association of Clock gene polymorphism with annual cycle timing in stonechats
Clk locus specific and genome wide diversity of stonechat populations relative to breeding latitude. Gene diversity at the polymorphic Clk locus for the nine populations of this study is indicated by open circles (left axis); genome wide nucleotide diversity (autosomal pi) is plotted by black squares (right axis) for five populations with available genome wide statistics54. Clk gene diversity is lower in the African populations breeding at the equator than in the populations that breed at higher latitudes in Europe and Asia.
