Turner Syndrome is a genetic disease that is only found in females. When any child is conceived, they are born with two sex chromosomes that determine the offspring's gender. Girls receive two "X" chromosomes. During child development, one of the X's is missing or formed abnormally. This abnormality determines if the female develops Turner Syndrome. Turner Syndrome is neither dominant nor recessive. This is because the chromosomal pair would be XO instead of XX like it should be. This would cause the disease to be chromosomal, not genetic.
