 A very few species (for example "Amphidromus perversus") show an equal mixture of dextral and sinistral individuals.In humans, chirality (also referred to as "handedness" or "laterality") is an attribute of humans defined by their unequal distribution of fine motor skill between the left and right hands.An individual who is more dexterous with the right hand is called "right-handed", and one who is more skilled with the left is said to be "left-handed".
