- Atypical Sex Chromosome Patterns
- Klinefelter's Syndrome, **Y: Caused by an extra X chromosome. Biological male with appearance of a male however less body hair; undeveloped genitals; long legs in relation to torso; infertile. Affects between 1 in 500-1000 males. Psychological effects include poor language skills affecting reading ability and passive temperament.
- Turner's Syndrome, XO: Caused by absence of X chromosome. Biological female, with appearance of female, however ovaries fail to develop; short, squat body with webbed neck.

- Studies
- Money and Erhardt (1972) - Bruce
- AIM: Reassigned sex of child to see if he could be successfully socialised as a female. METHOD: Boy accidently castrated as a baby, Money advised gender reassignment and treat him as a girl. However he reversed his earlier plastic surgery to become male and got married to a woman.
- RESULTS: Initially Money reported the case a success, and took this as evidence for his theory of neutrality. However later revelations suggests that it was not successful. CONclusion: Biological influences ore important than socialisation, being treated as a girl did not affect Bruce's male identity.
