When phenotypes do not match genotypes - unexpected phenotypic diversity and potential environmental constraints in icelandic stickleback
Divergent lateral plate phenotypes in stickleback represent one of only a few cases known, where a single gene underlies the phenotype under divergent selection between different habitats. However, the selection pressures leading to the repeated loss of lateral plates in freshwater are still not wel...

Divergent lateral plate phenotypes in stickleback represent one of only a few cases known, where a single gene underlies the phenotype under divergent selection between different habitats. However, the selection pressures leading to the repeated loss of lateral plates in freshwater are still not well understood. By genotyping 838 individuals from 9 independently colonized lakes and 1 marine population in Iceland, we found 1) that only in some lakes are phenotypes associated with the expected genotype and 2) that the independent repeated occurrence of a rarely described plate phenotype is expressed in the absence of an allele that is usually associated with this phenotype. This suggests that either other genes such as modifiers might be under divergent selection between lakes or that lateral plate expression in these populations is restricted due to environmental constraints. |
