Genetic Factors
- Twin and Adoption
- A01
- Twin studies with MZ and DZ, if
MZ more alike in aggression than
DZ assumes genetic link as MZ
share all genes, DZ only half
- If positive correlation
between child and
biological parents
aggressive behaviour
suggests bio.
- If positive correlation between
child and adoptive parent,
assumes environment not bio
- MILES AND CAREY- studied
adoptive boys with criminal
convictions. many had bio
parents with criminal convictions
- Twin studies with MZ and DZ, if
MZ more alike in aggression than
DZ assumes genetic link as MZ
share all genes, DZ only half
- A02
- Support...
- MILES AND CAREY-
meta analysis 24 adoption,
found strong genetic and
environment in younger,
and strong genetic in older
individuals
- RHEE- 51 adoption, strong
correlation of genetics and
aggression/antisocial behavior
- MILES AND CAREY-
meta analysis 24 adoption,
found strong genetic and
environment in younger,
and strong genetic in older
individuals
- However...
- Mostly self-report. when
observattional, less correlation. so
method used has effect on findings
- May be other factors
involved, eg age
- PLOMIN- found no differnce in
correlation between MZ and DZ

observattional, less correlation. so

- A01
- Genes
- A01
- MAOA- gene that
regulates metabolism
of seratonin. low levels
= aggression. so may
be due to this gene
- BRUNNER- violent Dutch family,
low levels of MAOA, faulty MAOA
gene so seratonin not regulated.
- CASPI- two variants, one with high levels of
MAOA and one with low. low=more aggressive
ONLY if maltreated as child. assumes
environment is factor, not all genes
- MAOA- gene that
regulates metabolism
of seratonin. low levels
= aggression. so may
be due to this gene
- A02

- YOUNG- rodents, eliminated a single gene,
the mutation showed to cause aggression.
can be seen in mice. Also exists in humans
but its function isnt known

- However...
- VALID? focuses on those
convicted of violence but only
represents minority. also,
murder is ONE violent act not
constantly aggressive
- many genes which
contribute to behaviours
so hard to name just one.
also, may be due to SLT
and environment
- BRENNAN- genetics significant in
case of petty not violent crimes

convicted of violence but only

- A01
- Violent Crimes
- A01
- Inherited temperment/ personality makes
people more likely to commit violence.
research shown clear evidence of genetics
and environment as high rates of criminal
violence when both bio and adoptive
parents are violent

- A02
- HOWEVER... ethics, labelling someone as a threat
based on genetics. as evidence isnt conclusive.

- CULTURE-
!kungsan tribe
- ANIMAL- young,
generalisable?
- SOCIALLY SENSITIVE- may
cause distress talking about crimes
commited or giving up child.
- REAL LIFE- led to
genentic engineering
to prevent crimes.
