Why did the XYY chromosome theory?
Why did the “XYY” chromosome theory fall out of favor as an explanation for criminal behavior? Most criminals do not have XYY and everyone with XYY is not a criminal. Suicide bombers in Iraq are accorded high praise by those who oppose an American presence in the Middle East and are considered heroic warriors.
Is there an XYY chromosome?
The chromosomes contain genes, which determine an individual’s characteristics, such as eye color and height. Boys typically have one X chromosome and one Y chromosome, or XY, but boys with XYY syndrome have an extra Y chromosome, or XYY. XYY syndrome is not caused by anything the parents did or did not do.
What type of mutation is XYY syndrome?
