How does a person inherit Turner Syndrome?

Turner Syndrome is also known as Ullrich Turner Syndrome. This syndrome is only prevalent in females because it affects the X's in the sex chromosome pair. Girls without Turner Syndrome usually have two X chromosomes but girls with Turner Syndrome only have one unaffected chromosome and one missing or abnormal. Females that have Turner Syndrome normally can't have children due to their infertility caused by the disorder. This makes it impossible for the mother to be "sick" with the disease and have a child. This means that Turner Syndrome is not a genetic disease and is neither recessive nor dominant. Turner Syndrome can be caused by nondisjunction which is when the sex chromosome pair doesn't separate when the sperm and egg form. It is caused by a mutation during meiosis and is not inherited because it is a random event that happens during a cell division process.
