Best Answer

Turner syndrome is the result of one of the two X chromosomes being missing or damaged in some or all cells. These chromosomes are the sex chromosomes, which determine whether a person will be male or female. As people with Turners only have an X chromosome and no Y chromosome they are born female.

Explain how nondisjunction results in cells with abnormal numbers of chromosomes?
