What happens if a female with Turner Syndrome has the X chromosome inactivated?

What determines the sex of an individual?

What determines whether a mammal will be male?
In mammals, the presence or absence of a Y chromosome controls the sex of the individual.
How abnormal number of any chromosome gets into gamete?
That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.
What chromosome does cystic fibrosis effect?
The gene on chromosome 7 produces a protein called cystic fibrosis trans-membrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease.
What happens to the chromosome of a cell in order for mitosis to begin?
