Answer 1

To identify a genetic disorder from a karyotype, it is essential to look for abnormalities such as extra chromosomes or missing chromosomes.

In humans, Down syndrome is the most common chromosomal disorder and is associated with an extra copy of chromosome 21 (trisomy 21). Therefore, if the karyotype shows an abnormality in chromosome pair 21, that is indicative of a genetic disorder.

Thus, based on the available options, the correct answer is:

**Chromosome pair 21**.
