| Video Discription | “Seriously You’re Left Handed?” #wait. The genetics of left-handed people differ from those of right-handed individuals, although the full extent of these differences and the mechanisms behind them are not yet fully understood. Left-handedness, observed in about 10% of the global population, has long intrigued scientists seeking to uncover the genetic and environmental factors that contribute to this trait. Genetic Variants: Research indicates that several genetic variants are associated with left-handedness. Studies have identified certain genes, such as LRRTM1 and PCSK6, that may play a role in determining hand preference. These genes are involved in brain development and asymmetry, suggesting a genetic influence on handedness. Brain Asymmetry: Left-handed individuals often exhibit different patterns of brain asymmetry compared to right-handed people. For instance, left-handers may have more symmetrical brain hemispheres, affecting the lateralization of brain functions such as language and motor skills. This asymmetry is thought to be influenced by genetic factors. Familial Patterns: Handedness tends to run in families, indicating a hereditary component. Children of left-handed parents are more likely to be left-handed themselves, although the exact mode of inheritance is complex and not solely determined by a single gene. Polygenic Trait: Left-handedness is considered a polygenic trait, meaning that multiple genes contribute to its expression. The interaction between these genes and environmental factors further complicates the genetic landscape of handedness. #lefthanded #brain [Vgk2lbO8co4] |
