• assume gender and sex interrelated
• Differences between sexes, attributed to anatomical, differences, chromosomes and hormones
• Focuses on int factors
• 23 pairs of chromosomes
• Fem = XX , male = XY
• Normal excel produced by ovary have X chromosome
• half sperm cells carry X Chr + other y
• Abbys sex determined by sperm that fertilises eggs
• during prenatal development all genitals, start the same
• Both males and females have external genitalia that looks female
• Eight weeks into gestation SRY gene activated on Y chromosome
• Causes testes to produce male hormone testosterone
• Male gen develops
Direct link between individual chromosomal sex + external genitalia ( v/p) + int gen (O/ T )
• xx -> ovaries + vagina (fem ch)
• gen trans expl how indiv acquire sex
• Asp of gender bc links between genes + hormones + genitalia
AO3:
S. MONEY
• case study - Bruce / Brenda
• Gen inf of chromosomes overriding f
W; case study
• idiographic -> lacks pop val
W; biologically deterministic
• chromosomes -> more masculine + fem
• free will - choose to go ag natural gender
W: underemphasises social and psychological influence
• SEAVEY
, Aytipical chromosomes
AO1:
• normal sex chromosomes - male = XY females = XX
• Atypical due to non-disjunction in meiosis
KLINEFELTER’S
• affects males
• XY -> XXY
• physical characteristics: reduced body hair some breast development during puberty, long g limb
• Psychological characteristics: poorly developed language skills and reading ability, shy
TURNER’S
• affects females
• physical characteristics: no menstrual cycle, no breast development at puberty, infertile
• psychological characteristics : higher than average reading ability + socially immature
AO3:
S: DE LISI ET AL
• 11 KFS + 11 non - KFS interview , cog test + MRI scan
• smaller frontal + temp lobes
• Lang deficits
S: STUDIES USEFUL
• Nature + nurture
W: CAUSATION
• environ inf
• Turners - treated immaturely
S: DIAGNOSIS
