Normally males have the XY chromosomes and females have XX chromosomes. Occasionally males are born with an extra Y chromosome and are XYY meaning they’re super masculine. This is called Jacobs Syndrome.
The Y chromosome is for masculinity.
Would these individuals be very attractive to women?

From what i remember about it there are no behavioural differences, but people with XYY are more likely to have difficulty learning, so i wouldnt say so, no.
