GYNANDROMORPH, a term used in biology to denote an intersex of the mosaic type, i.e., one side or part of the body is male, the other female. A gynandromorph is to be distinguished from an hermaphrodite (q. v.) in which the entire animal is inter mediate between male and female. Gynandromorphs occur in several groups of animals, notably in insects and birds, but not in mammals. (See SEX.)
