How does research into atypical sex chromosome patterns support the nature nurture debate? (AO3)
When comparing people who have these syndromes and normal people we can identify differences between the two groups. Therefore, it will be logically inferred it has a biological basis as a result of abnormal chromosomes.
Describe the counter evidence for supporting the nature side of the debate (AO3)
The correlation may not mean causation
It may be that the environment and social influences are responsible for differences in behaviour. Therefore, wrong to assume all down to nature.
Explain how research into atypical sex chromosome patterns has a real world application (AO3)
Continued research into atypical sex chromosome patterns is likely to lead to earlier diagnosis. An Australian study into 87 people with klinefelters syndrome diagnosed from an early age. This was shown to benefit them as they could manage their syndrome from an earlier age.
