gynandromorph An animal that possesses both male and female characteristics because it is genetically a mosaic, i.e. some of its cells are genetically male and others are female. This phenomenon is found particularly in the insects but also appears in the birds and mammals; it is often due to the loss of an X chromosome in a stem cell of a female (XX), so that all tissues derived from that cell are phenotypically male. Compare intersex.
gynandromorph An organism in which part of the body is male and the other part female.
