There are no chromosomal disorders

Answer 1

To identify a genetic disorder using karyotype analysis, it is important to look for abnormalities such as extra chromosomes (aneuploidy) or chromosomal deletions or duplications. Common examples include Down syndrome, which is associated with an extra chromosome 21.

Given the options provided, if a karyotype displays an abnormality in chromosome pair 21, it would indicate a genetic disorder such as Down syndrome (Trisomy 21).

Therefore, the correct response to the question is:

**Chromosome pair 21**
