Hi! In my group we for sure have some ☺️

This study nicely highlights the need of experimental approaches to test for associations found in genomic studies 🐟

Stay tuned for our exploration on ecological relevant traits of these inversions!

Moreover, there were no strong effect of inversion genotype across salinity treatments in body size, suggesting that salinity alone might not be the selective force acting on them and the need to explore further aspects of stickleback biology 5/

Across the three inversions, genotype frequencies follow a Mendelian ratio suggesting that there are no lethal effects when inversions are in homozygous state. 4/

Given their association with marine-freshwater divergence, we hypothesized that saltwater could be a potential selective force acting on these inversions. Thus, our crosses were grown in freshwater and saltwater 3/

Three inversions have been associated with marine-freshwater divergence in this system but little is known about their effects. So, we decided on assesing survival and body size using experimental crosses 2/
