The gender associated with "yy" is male. This refers to XYY syndrome, a genetic condition in males where an extra Y chromosome is present.
- XYY syndrome is a condition found only in males. This occurs when a male receives an extra Y chromosome during fertilization, resulting in a total of 47 chromosomes instead of the typical 46.
- People with XYY syndrome may have some physical and developmental differences, but most individuals lead normal lives.
Note: A YY individual (without an X chromosome) is not possible in humans. The X chromosome carries essential genes for development, and its absence would be incompatible with life.
