Describe how the karyotype of an XXY human would differ from that of an XO human?
The karyotype of an XO human would be deficient one X chromosome, compared to that of a normal female, and it would result in a female. Normal human females only use one X chromosome, whereby one is inactivated, which is why an XO human is viable. An XXY human would have one extra X chromosome as compared to that of a normal male, and it would result in a male. Again, an X chromosome is inactivated, which is why an XXY human is viable. XO is referred to as Turner Syndrome. XXY is referred to as Klinefelter Syndrome.
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.
Can boys get turner syndrome?
Most girls are born with two X chromosomes, but girls with Turner syndrome are born with only one X chromosome or they are missing part of one X chromosome. The effects of the condition vary widely among girls with Turner syndrome. It all depends on how many of the body's cells are affected by the changes to the X chromosome.
Can the environment cause turner syndrome?
As far as I know, the environment is not believed to be a cause of Turner syndrome.
An individual with Turner syndrome appears male and has 1 Barr body?
A person with Turner syndrome typically has female characteristics, but may have some physical features mirroring male traits, such as a broad chest or a low hairline. The presence of one Barr body in their cells is normal, as individuals with Turner syndrome have a single X chromosome.
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).
What chromosome is affected in Turner Syndrome?
The chromosomes which are affected in Turner's Syndrome is the sex chromosomes. A normal female individual has 2 X sex chromosomes. In Turner's Syndrome, a woman only has one X chromosome and is missing the other. Thus, a woman with Turner's Syndrome has the sex chromosomes X0.
Are there different types of turner syndrome?
There are 3 types of Turner syndrome Classic Turner syndrome - 45X - second X chromosome missing from all cells. Mosaic Turner syndrome - 45X/46XX - second X chromosome missing from some cells. The third type of Turner syndrome is when the second X chromosome is damaged or only partly missing.
What does a female have if she only has one chromosome?
Turner Syndrome
Turner's syndrome always results in female offsprings why?
Because people who have Turner syndrome have one X chromosome instead of the two other females have. As they do not have a Y chromosome, they are female.
What are the 3 major chromosomal disorders?
The three major chromosomal disorders are Down syndrome, Turner syndrome, and Klinefelter syndrome. Down syndrome is characterized by an extra copy of chromosome 21, Turner syndrome involves a missing or incomplete X chromosome in females, and Klinefelter syndrome is caused by an extra X chromosome in males.

Which type of mutation can lead to the loss of gene chromosome?
The term is monosomy, in which one chromosome of a pair is missing. Turner's Syndrome is an example of monosomy, in which there is only one sex chromosome, which is the X chromosome. Humans with Turner's Syndrome are female, but sterile. The genotype of the sex chromosomes in Turner's Syndrome is XO, in which O represents a missing chromosome.
A female with only one x chromosome has?
Turner Syndrome

A karyotype would be unable to Turner syndrome?
A karyotype can detect Turner syndrome by revealing a single X chromosome in females (45,X). This genetic condition is characterized by the absence of one X chromosome, which is visible on a karyotype analysis.
What lacking an X chromosome and are designated XO?
Girls with Turner's syndrome
