It doesn't. Mud thrown once sticks no. Someone back in the 60's thought that it did - even though their statistical moderation was off. No connection has been found linking criminality with any form of aneuploidy. http://www.wellcome.ac.uk/Education-resources/Teaching-and-education/big-picture/all-issues/sex-and-gender/articles/wtx028518.htm
The XYY chromosome theory fell out of favor as an explanation for criminal behavior because subsequent research did not support a direct link between XYY genotype and criminal behavior. It was found that the association was weak and other factors such as social environment and upbringing play a more significant role in shaping criminal behavior.
XYY syndrome is an aneuploidy of the sex chromosomes in which a human male receives an extra Y chromosome. A popular misconception in the 1960s and 1970s that XYY males were more prone to criminal behavior led to several novels and TV series which exploited the idea with little regard to the science.
Current research on XYY syndrome is focused on understanding the link between the extra Y chromosome and the associated physical and behavioral characteristics of individuals with the condition. Studies are also exploring potential treatments and interventions to address the challenges that individuals with XYY syndrome may face, such as learning difficulties and behavioral issues. Additionally, research is investigating the genetic mechanisms underlying XYY syndrome to improve diagnosis and management of the condition.

XYY Syndrome
There are seven possible genetic sexes: XX = female XY = male X = female with Turner syndrome XXX = female with X-trisomy XXY = intersex with Klinefelter syndrome XYY = male with 47,XYY syndrome XXYY = male with 48,XXYY syndrome
You would have 47 chromosomes because you would have the normal 46 but one extra y with the sex determing pair of chromosomes which would make you have super male syndrome.
Yes, Klinefelter's syndrome is due to the XXY genotype.
Jacobs syndrome, also known as XYY syndrome, affects males. It is a genetic condition caused by the presence of an extra Y chromosome in males.
XYY syndrome is caused by an extra Y chromosome in males. This condition typically occurs due to a random error in cell division during either the formation of the sperm or the egg. It is not inherited and does not have a clear genetic cause.
The discovery of the 47 XYY syndrome was first reported by Patricia A. Jacobs and J.A. Strong in 1961. They described a male with an extra Y chromosome, leading to the identification of this chromosomal abnormality.
Super male syndrome, also known as XYY syndrome, occurs when a male has an extra Y chromosome, resulting in a chromosomal pattern of XYY instead of the typical XY. This genetic condition arises during the formation of sperm, where an error in cell division leads to the extra Y chromosome. It can be passed from an affected father to his offspring if he contributes the extra Y chromosome during fertilization, resulting in a son with the XYY genotype. This syndrome is not inherited in a traditional Mendelian manner but rather occurs as a random event during sperm development.
