Technical term used in fields such as biology, mathematics, and statistics to describe lack of symmetry. Not an everyday word.
Asymmetry can be observed in the body of this organism.
In statistics, the asymmetry of a distribution is expressed by skewness.
Compound of 不 (fu, 'not') + 均斉 (kinsei, 'symmetry, balance'). 均斉 itself is a less common word for symmetry, composed of 均 (kin, 'equal') and 斉 (sei, 'uniform').
