What can not be determined from a karyotype?

Which of the following can you determine from a human karyotype?

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.

What 3 things can a karyotype show?

A karyotype test looks at the size, shape, and number of your chromosomes. Chromosomes are the parts of your cells that contain your genes. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color.

What are the limitations of a karyotype?

Some of the limitations of karyotype analysis include its requirement of a sample containing fresh viable cells and its low sensitivity for the detection of abnormalities, requiring a minimum of 5–10% of cells examined to contain the abnormality for optimal detection.
