- Chromosomal inversions contribute to genetic diversity and reproductive isolation between evolutionary lineages, impacting speciation.
- In studying the long-snouted seahorse, researchers identified two significant chromosomal inversions that vary in frequency among different geographic lineages and ecotypes.
- These inversions are suggested to be ancient polymorphisms with one maintained through divergent selection and the other through pseudo-overdominance, revealing complex interactions influencing reproductive traits and evolutionary dynamics.
Structural variants (SVs) (i.e., deletions, insertions, duplications, and inversions) are now known to play an important role in phenotypic variation, and consequently in processes such as disease determination or adaptation to a new environment.

GWAS are challenging, with increasing, but still limited, use in evolutionary biology. We used redundancy analysis (RDA) as a complimentary ordination approach to single- and multitrait GWAS to explore the molecular basis of pigmentation variation in brown trout (Salmo trutta) belonging to wild populations impacted by hatchery fish.

- The study looked at how watching TV affects toddlers' emotions and behavior in different cultures.
- Researchers found that more TV time was linked to kids being more emotional, aggressive, and having trouble paying attention.
- However, the way TV affects these issues can change depending on the culture the child comes from.
