Question

I'm looking at two karyotypes, one for a person with Klinefelter's Syndrome and another with Patau's. What is the karyotype notation for them? I don't understand what I looked up online. Any help is appreciated. Thanks!

Answer 1

Klinefelter's Syndrome is represented by a karyotype of 47, XXY, while Patau's Syndrome is represented by a karyotype of either 47, XY+13 or 47, XX+13.

Step-by-step explanation:

Klinefelter's Syndrome is a genetic condition that occurs when a male has an extra X chromosome, resulting in a karyotype of 47, XXY. Patau's Syndrome, on the other hand, is caused by an extra copy of chromosome 13, resulting in a karyotype of 47, XY+13 or 47, XX+13, depending on the sex of the individual. Let me break it down for you:

Klinefelter's Syndrome:

1. Typically occurs in males
2. Extra X chromosome (XXY) is present
3. Karyotype notation is 47, XXY

Patau's Syndrome:

1. Can occur in both males and females
2. Extra copy of chromosome 13 is present
3. Karyotype notation is either 47, XY+13 or 47, XX+13
