Bilateral; two-sided; mutual; interchanged.

Reciprocal obligations are duties owed by one individual to another and vice versa. A reciprocal contract is one in which the parties enter into mutual agreements.

Reciprocal laws are statutes of one state that give rights and privileges to the citizens of another state if that state extends similar privileges to the citizens of the first state. A common example is the Reciprocal Enforcement of Support Act, which is a uniform law adopted in a majority of jurisdictions, by which a tribunal in the state where a wife or mother resides is able to commence proceedings for child support against a husband or father who resides in another state.

The number by which a given number must be multiplied to get a result of one. The reciprocal of one-half, for example, is two.

Mathematically the reciprocal of x is 1/x. See also translocation.

• r. crosses — matings of two phenotypes in which both the male and the female of both phenotypes are crossed, usually to detect sex linkage.
