Sympatric Arctic charr morphs (Salvelinus alpinus) from two connected Icelandic lakes

The genome-wide differentiation among four Arctic charr (Salvelinus alpinus) morphs in two Icelandic lakes (Thingvallavatn and Ulfljotsvatn) was studied using SNPs acquired via ddRADSeq. This is part of a project that also examined the phenotypic variation in sympatric charr morphs in the lake system using geometric morphometrics and diet analysis.
