Document Summary
Children begin to prefer sex-typed toys between ages 12 and 18 months. At the same age, children are unable to match sex-typed toys (vehicles and dolls) with male or female voices, suggesting they have not yet been socialized to think of toys as male or female . Reimer"s story suggests our biological sex may influence our ultimate sense of being a man or woman more strongly than how we are raised. 355 b. c. , aristotle argued sex of a child was result of temperature of semen at conception: hot semen male, cool semen female. Individual"s genetic sex begins with sex chromosomes inherited from two parents. Mother provides x chromosome: one of two types of sex chromosomes; individuals with two x chromosomes will usually develop into females. Fathers determine offspring"s sex by providing either another x or y chromosome: one of two types of sex chromosomes; individuals with a y chromosome will usually develop into males.
