1. If you are referring to the XY chromosome, in males it is called KLinefelter's syndrome, with XXY genotype.
2. Trisomy 21 is called Down's Syndrome.
3. Turner's Syndrome, or Monosomy X

#! is XYY; males that are unusually agressive because of high testosterone. Many are incarcerated.
trisomy 21 is Down Syndrome- retardation, heart disease, extra skin folds in eyes.
Turner's Syndrome is 1 X, not two on 23rd- shorter than average, sterile, occsionally retardation, skin flaps on neck
