Heterogeneous evolution of effective recombination landscapes across percomorph fishes

A chromosomal inversion acts as a hotspot for divergence in multiple ecologically relevant traits

Chromosomal inversions are proposed to aid local adaptation to divergent habitats when there is gene flow by creating regions of low recombination that can maintain tight linkage between multiple locally adaptive alleles. However, key theoretical predictions about the role of chromosomal inversions in local adaptation...

A 16-bp deletion in the first intron of Eda is not responsible for the loss of lateral plates in threespine stickleback

Results suggest that the causative mutation is either somewhere else within the 1.4 kb region or that LP3621 interacts with another mutation in the Eda haplotype to cause the loss of lateral plates in threespine stickleback.
