If one of sex chromosomes is missing. Normal-XX Turner- XO
46,XXY or XXY for males; see the link below.
The most common type of chromosomal disorder is the Down syndrome caused by an added copy of chromosomes 21. More common chromosomal disorders are Klinefelter's syndrome and Turnerâ??s syndrome.
Nothing 'causes' Turner Syndrome it is simply random geneticsGenetic mosaicism is most often implicated alongside nondidjunction and partial monosomy
Klinefelter syndrome is a chromosomal condition that only affects males and is characterized by a male having an additional X chromosome (XXY) in cells. This chromosome abnormality occurs when there is an error in cell division, resulting in an extra copy of the X chromosome.
Turner syndrome causes short stature in girls because they are missing part or all of one of the X chromosomes. This chromosome abnormality affects growth and development, leading to a shorter overall stature. Additionally, hormonal imbalances in Turner syndrome can affect bone growth and result in reduced height.
Girls born with Turner's syndrome are born with only one x chromosome instead of the average two x chromosomes. Mood swings are apparent in all females, however, a chromosomal disorder such as Turner's syndrome can cause one's emotions and chemical make-up to be a little out of whack and this causes more frequent, intense mood swings. This could also be linked to a personality disorder as well, not just the fact that people with Turner's syndrome are missing their second x chromosome.
Klinefelter's syndrome is caused by the presence of an extra X chromosome in males (XXY), typically resulting in developmental and hormonal differences. Turner syndrome is caused by the complete or partial absence of one of the X chromosomes in females (X0), leading to underdeveloped ovaries and infertility. Both conditions occur due to chromosomal abnormalities during conception.
non disjunction of sex chromosomes
Turner's syndrome is when a woman is missing a chromosome on either gene 21 or 22. Pretty sure it's 22. This causes her not to be able to have children. Hope this helps.
Nondisjunction is the disappointment of homologous chromosomes to detach accurately during meiosis. This outcomes in the creation of gametes containing a more noteworthy or lesser chromosomal sum than typical ones. Therefore the individual might create a trisomal or monosomal condition.
You are simply born with it, no causes have been discovered yet.
The most common autosomal abnormality seen in a person is Trisomy 21, which causes Down syndrome. This occurs due to an extra copy of chromosome 21, leading to developmental delays and physical characteristics like slanted eyes and a flat facial profile.
