If a child has three copies of the 21st chromosome instead of two, it results in Down syndrome. Turner's syndrome is a genetic disorder where a female is born with only one X chromosome, while mitochondrial syndrome is a rare genetic disorder affecting the body's energy production due to mutations in mitochondria. Bowlby's syndrome is not a recognized medical term or condition.
