What else can I help you with?
Can a girl with a karyotype of 46XX still be diagnosed with Turners?
No, individuals with Turner syndrome typically have a karyotype of 45X. If a girl has a karyotype of 46XX, she would not be diagnosed with Turner syndrome.
What would be a concern when viewing a karyotype?
A concern when viewing a karyotype would be the presence of abnormal chromosome numbers or structures, which can indicate genetic disorders, such as Down syndrome or Turner syndrome. It is important to accurately identify and interpret any chromosomal abnormalities present in a karyotype to understand the implications for an individual's health.
Why do you think a doctor would be interested in looking at a person's karyotype?
A doctor might be interested in looking at a person's karyotype to identify chromosomal abnormalities such as Down syndrome or Turner syndrome, to diagnose genetic disorders or certain types of cancer, or to assess infertility issues. Karyotyping allows them to visually analyze the number, size, and shape of an individual's chromosomes.
WHAT NOTATION WOULD YOU USE TO CHARACTERIZE PATIENT AS KARYOTYPE?
Patient A has Down Syndrome or a trisomy 21. The notation would be 47xy+21.
If you are a girl and you have turner syndrome when will your growthplates close in your feet?
In Turner syndrome, growth plates may close earlier than in typical development, usually around mid to late teens. This can result in shorter stature and differences in bone development compared to individuals without Turner syndrome. Regular monitoring and hormone therapy can help manage these differences.

What type of diagnosis is from a karyotype?
A karyotype tells you if you have the normal ammont of chromosomes (46 for humans), it can also tell you if you have more or less and if this is the case what it is that you have. The most common syndrome would be Down Syndrome, or trisomy 21. Down Syndrome is also called trisomy 21 because if you look at a karyotype from someone that has this syndrome then they have three coppies of the 21st chromosome.
What type of picture would a biologist look at to determine whether a fetus has Down syndrome?
a Karyotype
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.

Patient A has Down Syndrome or a trisomy 21. The notation would be 47xy+21.
Are heart problems the norm for Turner syndrome women?
Heart problems are more common in women with Turner syndrome, although I do not know if I would say they are the norm.

In Turner syndrome, growth plates may close earlier than in typical development, usually around mid to late teens. This can result in shorter stature and differences in bone development compared to individuals without Turner syndrome. Regular monitoring and hormone therapy can help manage these differences.
A karyotype would be unable to determine what?
A karyotype would be unable to determine specific gene mutations or variations that may affect an individual's traits or health. It also cannot provide information about complex genetic conditions or environmental influences on gene expression.
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 serve cases of turner's syndrome?
A severe case of Turner syndrome would be if someone who has many of the characteristics associated with it, especially if these characteristics were the possible problems with the heart, kidney or thyroid.
