when you look at a karyotype you can see th echromosome pairing. If there are short or long chromosomes you can see them. You can also see if there are extras of any of the pairs.

Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra, missing, or abnormal positions of chromosome pieces can cause problems with a person's growth, development, and body functions.
Normal: There are 46 chromosomes that can be grouped as 22 matching pairs and 1 pair of sex chromosomes (XX for a female and XY for a male).
The size, shape, and structure are normal for each chromosome.
Abnormal: There are more than or less than 46 chromosomes.
The shape or size of one or more chromosomes is abnormal.
A chromosome pair may be broken or incorrectly separated
