Trisomy 21 Down syndrome xxy kleinfelter syndrome and xo turner syndrome are all caused by?
Nondisjunction
-Trisomy 21(Down syndrome) means there are 3 chromosomes on the 21st pair of chromosomes.
-Kleinfelters (XXY) means there is an extra chromosome on the 23rd pair(where the sex chromosomes lie).
-Turner Syndrome(XO) On the 23rd pair, there is no Y or second X chromosome. The female can survive with this.

What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Which of the following are example(s) of trisomy---Turner Syndrome Down's Syndrome or Klinefelter's Syndrome?
Trisomy means having three copies of a chromosomes. Turner's syndrome is NOT an example of trisomy. Someone with Turner's syndrome has only one X chromosome. Down's syndrome IS an example of trisomy. Someone with Down's syndrome has 3 copies of chromosome 21. Klinefelter's syndrome is a tricky one. On one hand, it would be considered trisomy because they have 3 sex chromosomes. However, they are not all the SAME sex chromosomes. Someone with Klinefelter's has 2 X chromosomes and one Y chromosome.
What is an example of a disorder associated with an error in the number of chromosomes present?
Down syndrome (trisomy 21) is a disorder associated with an error in the number of chromosomes present. Other examples of disorders associated with an error in the number of chromosomes are Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome), Triple X syndrome, and Klinefelter Syndrome.

What is the different autochromosomal abnormalities?
Common autosomal chromosomal abnormalities include Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), Patau syndrome (trisomy 13), and Turner syndrome (monosomy X). These abnormalities result from errors in chromosome number, leading to characteristic physical and developmental features. Diagnosis is often made through genetic testing such as karyotyping or chromosomal microarray analysis.
What are some diseases non-disjunction causes?
No " following, but a condition such as trisomy 21, Downs syndrome, is caused by nondisjuction. The chromosomes fail to separate properly and one child is left with an extra chromosome number 21. The potetial other children that could have been born of this nondijuction event, those with only one chromosome 21, are not viable.
What heart problems are caused by Turner syndrome?
Cardiovascular malformations are well-recognized congenital anomalies in Turner syndrome. Dilation and dissection of the aorta are reported in approximately half of women with Turner syndrome
What are the similarities and differences between Down syndrome and Turner syndrome?
Down syndrome is caused by an extra or part of an extra 21st chromosome while Turner syndrome is caused by an absence in one or part of the sex(X) chromosome.Down syndrome can occur in both male and femalewhile Turner syndrome only occurs in female.People with Down syndrome tend to have a lower than average cognitive ability.Both Down syndrome and Turner syndrome are at higher risk for having medical conditions such as heart problems.
Are klinefelter syndrome and Turner syndrome results of nondisjunction of autosomes?
No, Klinefelter syndrome and Turner syndrome are the result of nondisjunction of sex chromosomes. Klinefelter syndrome is caused by an extra X chromosome (XXY), while Turner syndrome is due to a missing X chromosome (XO).
Can the environment cause turner syndrome?
As far as I know, the environment is not believed to be a cause of Turner syndrome.
What is a genetic condition that can result when chromosomes don't separate correctly during meiosis?
Trisomy 21 (Down's syndrome), Turner's syndrome (XO), and Klinefelter's syndrome (XXY) are a few examples of genetic disorders that can result when chromosomes don't separate correctly during meiosis.
How many sexes are possible in chromosomes?
There are seven possible genetic sexes: XX = female XY = male X = female with Turner syndrome XXX = female with X-trisomy XXY = intersex with Klinefelter syndrome XYY = male with 47,XYY syndrome XXYY = male with 48,XXYY syndrome
