Genetic theories

Question 1

what is XXY theory

Answer 1

This theory suggests that some crime might
be attributable to a chromosomal abnormality.

There are a variety of chromosome abnormalities, some of
which involve the presence of extra chromosomes, one
such condition, known as ‘XYY’, involves the presence of an
extra Y chromosome.

XYY men, sometimes called ‘super males’ have been of
interest to criminologists because of the suggestion that
they are more aggressive and more inclined to be violent
than males with a single Y chromosome.
