Transcribed Image Text:**What is shown here?**
This image displays a karyotype, which is an organized profile of a person's chromosomes. The chromosomes are arranged and numbered by size from largest to smallest. This karyotype appears to show human chromosomes, which typically display 22 pairs of autosomes and one pair of sex chromosomes.
- **Chromosomes 1-22:** These are the autosomes, which are chromosomes that do not determine sex. Each pair is made up of one chromosome from each parent.
- **Sex Chromosomes:** The 23rd pair consists of the sex chromosomes, which are labeled as either "X" or "Y". This determines the biological sex of an individual.
The chromosomes are stained to reveal characteristic patterns of light and dark bands, which help identify them and distinguish them from each other. These banding patterns are useful for identifying genetic disorders by detecting anomalies, like extra, missing, or irregular chromosomes.
Below the image, there is a prompt labeled "Multiple Choice," suggesting that this may be part of an educational exercise or quiz on genetics.
