Chromosomal influences on gender development Flashcards
(14 cards)
what are examples of aytypical chromosome patterns
Klinefelters syndrome
Turners syndrom
what are atypical chromosome patterns used to demonstrate
demonstrates the role of biological factors in the development of gender as both disorders have different genetics to ‘normal’ men and women and therefore the effect of chromosomes on gender can clearly be highlighted
what gender is affected by Klineflelters syndrome
MALES
what happens to a mans chromosome pattern when he has Klinefelter’s syndrome
instead of XY theres an extra X chromosome therefore, males with Klinefelter’s syndrome has XXY chromosome pattern
what physical characteristics results from Klinefelter’s Syndrome
- reduced bodily hair
- some breast development
- underdeveloped genitals
what psychological characteristics results from Klinefelter’s Syndrome
- poorly developed language skills
- tendency to beocme upset easily
- passivity comapred to other boys
- a lack in sexuala ctivity
- issues w/executive functions — such as memory + problem solving
what happens to a woman’s chromosome pattern when she has Turners syndrome
woman have a chromosome pattern XO (no second chromosome) compared with the normal pattern XX
the aytypical development of turners syndrome leads to what physical characteristics
lack of menstruation, lack of breast growth and generally physically immature likenning to that of prepubescent girls
the aytypical development of turners syndrome leads to what psychological characteristics
higher than average literacy abilities, imapired cognitive functions such as memeory, spatial taks and mathematical bility and a difficulty fitting in
what reason is there for chromosomal influences on gender development
Klinefelter’s syndrome, turners syndrome lead to people with these syndromes to have characteristics that differentiate from the norm, suggesting chromosomes affect gender development
how many people are affected by Klinefleters syndrome
1 in 1000 people
how many people are affected by turners syndrome
1 in 5000 people
strength of chromosomal influence on gender development
P: Evidence from hormone replacement therapy (HRT) supports the role of chromosomes in gender development.
E: HRT is used to increase levels of sex hormones in line with an individual’s gender identity, which often leads to changes in both physical and, in some cases, psychological characteristics
E: Since chromosomes determine hormone production, and altering hormone levels can influence gender-related traits, this suggests that chromosomes play a key role in shaping gender development
L; This supports the biological explanation by highlighting the indirect but significant impact chromosomes have on both physical and behavioural aspects of gender.
limitation of chromosomal influences on gender development
P:A limitation of research into atypical chromosome patterns and gender development is its social sensitivity
E; Findings from this research could lead to individuals with conditions like Klinefelter’s or Turner’s syndrome being labelled or treated differently by society
E: This raises ethical concerns, as the research may unintentionally contribute to stigma or discrimination
L: Therefore, while the research provides valuable insights into gender development, it must be conducted and applied with caution to avoid negative social consequences.
