What can a karyotype tell you?
Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome). Careful analysis of karyotypes can also reveal more subtle structural changes, such as chromosomal deletions, duplications, translocations, or inversions.
How do you tell if a karyotype is male or female?
Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
What genetic disorders Cannot be detected by karyotyping?
