SEX. The physical difference between male and female in animals.
     2. In the human species the male is called man, (q.v.) and the female, woman. (q.v.) Some human beings whose sexual organs are somewhat imperfect, have acquired the name of hermaphrodite. (q.v.)
     3. In the civil state the sex creates a difference among individuals. Women cannot generally be elected or appointed to offices or service in public capacities. In this our law agrees with that of other nations. The civil law excluded women from all offices civil or public: Faemintae ab omnibus officiis civilibus vel publicis remotae sunt. Dig. 50, 17, 2. The principal reason of this exclusion is to encourage that modesty which is natural to the female sex, and which renders them unqualified to mix and contend with men; the pretended weakness of the sex is not probably the true reason.

These conditions are the result of various mutations of genes located on autosomes and/or sex chromosomes. For example, one type of ovarian dysgenesis is attributed to a mutation of an autosomal gene that regulates hormonal control of follicle growth.
