Going down to the cellular level, it occurs in meiosis when chromosomes fail to separate (nondisjuction). We get a set of chromosomes from our paternal side and the other set from out maternal side. For example, one of the gamete that may have came from our maternal side contains no chromosomes , O, when it should contain that chromosome x while from our paternal side we get a gamete containing the x chromosomes. This results in a XO, a sterile female when the normal sex chromosomes are XX or XY.

∙ 13y agoPeople have Turner syndrome because the second X chromosome is missing from all or some of their cells. This happens randomly at some time during cell division as an embryo/foetus I think. As far as I know, they do not know why the second X is missing. It happens in about 1 in 2,000 live female births.

∙ 7y agoNothing 'causes' Turner Syndrome it is simply random genetics
Genetic mosaicism is most often implicated alongside nondidjunction and partial monosomy

∙ 13y agoTurner syndrome is the deletion of the second X chromosome. As far as I know this is a random event and it is unknown why it happens.
Wiki User
∙ 12y agoNo, it is caused by Nondisjunction. That means the chromosomes didn't separated properly.

Who carries the Turners Syndrome Does it come from the female or male?
This is not a good question. The Turners Syndrome only occurs in women, and it is not inherited, because these women cannot have their own children. No causes have been discovered yet.

Why does an individual with Turners syndrome often NOT get diagnosed till adolescence?
Sometimes the person does not have obvious characteristics of Turner syndrome, so they do not get diagnosed as a child. When they become adolescent and do not go through puberty that is what leads the doctor to test the person for Turner syndrome.
Does Triple X syndrome occur because of nondisjunction?
yes
In Jacob syndrome did the nondisjunction occur in the mother or father?
Jacob syndrome, 49XYY, has to occur as a result of nondisjunction in the father. The Jacob Syndrome male would have received the X chromosome from his mother, and both Y chromosomes from the father (since the Y chromosomes can not possibly have come from the mother). Jacob Syndrome can be the result of nondisjunction in meiosis.
What is turners disease not turners syndrome that can affect males?

Can animals get klinefelters or turners syndrome as humans do?
Yes animals do sometimes have Turner's syndrome or Klinefelter's syndrome with similar characteristics as those observed in humans.
Why does turners syndrome affect so little?
not a very bad (effective) symptom
Is turner syndrome inheritable or random?
it is not inherited because a women with turners sydrome cannot have children so that means that its not inherited
Does turner syndrome have mental effect?
As a 19yr old female with Turner's Syndrome (diagnosed at 8yrs old), have never had any problems in school. There is usually no mental effect, however girls with turners may have problems with spatial problems and possibly math. However, I am in my second year of university, and have received an A in Linear Algebra, and have never had special treatment due to turners syndrome.
Does turner's syndrome occur in all cells?
No, only the gametes would be indicative of sterility. It is possible that the individual (though incredibly rare) to have "chimera" syndrome, where two non-identical twins merge to form one fetus. Turner's Syndrome is the absence of the male sex chromosome BTW. That chromosome carries little genetic information, and is possible during mitosis to "loose" it, but still create a mostly viable cell.

Will a turner syndrome baby live?
2% of unborn babies with Turners survive to birth. Babies with Turners who survive to birth live.
