handedness

[han′didnes]

a preference for use of either the left or right hand. The preference is related to cerebral dominance: left-handedness corresponds to dominance of the right side of the brain, and vice versa. Also called chirality, laterality.
Chemistry The left- or right-sidedness, or asymmetry of virtually everything in the universe from the ‘lowly’ molecule to highly complex organisms
Neurology A state of dominance of use of a preferred side, as in left-handed or right-handed

hand·ed·ness

(hand'ĕd-nĕs)
Preference for the use of one hand, most commonly the right, associated with dominance of the opposite cerebral hemisphere; may also be the result of training or habit.

handedness

The natural tendency to use one hand rather than the other for skilled manual tasks such as writing. Ambidexterity-the indifferent use of either hand-is rare. About 10% of people are left-handed.
