What are the 3 Biological genetic theories
Jacobs XYY, Twin studies, Adoption studies
How many more times likely are men with an extra ‘Y’ chromosome
10
What crimes where XYY males actually more likely to commit
Non-violent crimes
How many newborns have the extra ‘Y’ chromosome
1 in every 1000
What are limitations of Jacobs XYY
- ) Cannot categorise all crime - most also take physiological, Environment and social factors.
- ) Thielgard(1984) - Compared XYY and XY men and found aggression not linked to XYY.
In twin studies, what is Dizygotic (DZ)
when 2 eggs share half of the genetic material
In twin studies, what is Monozygotic (MZ)
When 1 egg shares all genetic material
What was Lange’s study
On 30 pairs of twins who were same sex. 17 were DZ and 13 were MZ. At least one of each pair was known to be criminal.
What were the results of Lange’s study
Lange found that 10/13 MZ twins were criminal compared to 2 out of the 13 DZ pairs
Limitations of Twin studies
- ) Different to separate the influence of genetics of social factors
- ) Small sample size
- ) Criminality could be down to nurture
What are 4 Physiological, Biological theories
Sheldon, Lombroso, Phineas Gage, Serotonin
What was the main point of Sheldon’s theory
Criminal behaviour links to a persons physical form.
What are the 3 types of body shapes Sheldon used
Endomorphic, Ectomorphic and Mesomorphic
What is Endomorphic
Fat and soft physical frame
What is Ectomorphic
Thin and fragile frame
What is Mesomorphic
Muscular and hard frame
What body type did Sheldon discover was the most likely to commit crime
Mesomorphic
What type of body type did Sheldon discover was the least likely to commit crime
Ectomorphic
Limitations of Sheldon Theory
- ) Body type not fixed
- ) Do mesomorphs get targeted
- ) Other body types can be criminal
What did Lombroso believe
Believed people with atavistic features such as long arms, Large jaws, extra fingers and monobrows - Were more likely to be criminal.
What was Lombroso’s study
He compared the physical characteristics of Italian prisoners to Italian solders.
What did Lombroso conclude from his study
That the prisoners were physically different.
How many atavistic features did a man need to have to be seen as criminal according to Lombroso
5 or more
How many atavistic features did a woman need to have to be seen as a criminal according to Lombroso
As few as 3
