In humans, certain functions such as language and spatial attention are lateralised, meaning they predominantly or exclusively performed by one hemisphere. Intriguingly, a significant portion of individuals exhibit mirrored pattern asymmetry, which has been attributed to genes, environmental influences, other factors. As lateralisation occurs across all major groups vertebrates, literature in species might provide valuable insights into these mechanisms. We reviewed current knowledge on the genetic factors underlying individual variability non-human vertebrates. Evidence basis for direction, strength asymmetries, both reported about dozen fish mammals. Nevertheless, careful examination revealed that none studies can definitively exclude influence non-genetic On hand, from past decade have suggested shape direction adaptive ways, aligning individual’s phenotype with local conditions. Overall, this review supports potential role differences environmentally driven plasticity shaping variance while highlighting gaps prevent precise disentanglement roles
