right-handedness

Right-handedness refers to a natural preference for using the right hand over the left for tasks such as writing, eating, and tool use. It is a common trait, with about 90% of people favoring the right hand. This preference is influenced by a combination of genetic, neurological, and environmental factors. The dominant hand is typically controlled by the brain's opposite hemisphere—in this case, the left hemisphere. Right-handedness reflects how our brain's specialized regions influence motor skills, contributing to efficient coordination and dexterity on one side of the body.
