Turner's syndrome describe the genetic makeup of someone with this disorder?
The karyotype is 45X or 45X/46XX depending on whether all or only some of the cells are affected.
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.
What are characteristics of Turners syndrome?
Depending on the type of Turner syndrome a person has, their karyotype is either: 45X - classic Turner syndrome - second X chromosome missing from all cells 45X/46XX - Mosaic Turner syndrome - second X chromosome missing from some cells. There is another type of Turner syndrome, but it has a more complicated karyotype and I am not sure what the karyotype is off the top of my head.
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 the karyotype of a person with turners syndrome look like?
There are a few types of Turner syndrome. The most common two are: 1) Classic - The karyotype is 45X. The second X chromosome in missing from all cells. 2) Mosaic - The karotype is 45X/46XX. The second X chromosome is missing from some cells. 3) There are other types of Turner syndrome in which the second X is only partly missing or it is partly damaged.

What does karytype mean?
Karyotype refers to genetic testing. A karyotype is a pictorial analysis of the number, form, and size of an individual's chromosomes. Cells from any nucleated replicating body tissue (except red blood cells, nerves or muscles) can be used for testing. The most commonly used tissues are white blood cells and fetal cells in amniotic fluid. The female karyotype is 46XX chromosomes and the male karyotype is 46XY chromosomes. Karyotypes can be used to determine the sex of a child and the presence of any gross chromosomal abnormalities

Turner's syndrome individuals have which genotype?
A person with Turner's syndrome has a missing or damaged X chromosome in some or all of their cells. There are two possible karyotypes with Turner syndrome - 45X (The second X is missing from all cells) and 45X/46XX (The second X is missing from some cells).
What is the normal genotype for a human female 44XX or 46XX?
true
How many chromosomes do hermaphrodites have?
True human hermaphroditism (when an individual has both ovarian and testicular tissue) is very rare - the documented karyotypes are 47XXY, 46XX/46XY, or 46XX/47XXY, and various degrees of mosaicism. This means that human hermaphrodites can have XXY sex chromosomes, or combinations where they have two genetically distinct populations of cells (chimera or mosaicism).

How many chromosomes does a praying mantis have?
All organisms contain 46 chromosomes. A praying mantis will also have 46 chromosomes. The males have 46XX and the females 46XY.
