However, the correlation for the estimated allele frequency differences (|AFD|) between humic and clear‐water lakes for both datasets was weaker ( r = 0.27), although highly significant ( p < 2.2 −16 ). 3.2 Genetic Diversity, Differentiation and Population Structure The evaluation of genetic diversity in the pool‐seq dataset revealed higher levels of genetic diversity in clear‐water lake populations than in humic lake populations (Table S2 ).
