The preference of being left-handed or right-handed is a biologically and genetically determined trait, but very complex that is not yet fully understood. However, it is believed that a combination of genetic and environmental factors may influence the determination of laterality, that is, the tendency to use one hand or the other.
Are you left-handed or right-handed?
Some studies suggest that laterality could be related to brain asymmetry, that is, the way the brain is structured and works. Most people have been shown to have a dominant cerebral hemisphere, which is responsible for hand control and other fine body movements. In most right-handed people, the left cerebral hemisphere is the dominant hemisphere, while in left-handed people it can be the right hemisphere or both hemispheres.
