Question

what kind of mutation does this image represent?

deletion
duplication
insertion
inversion
substitution

Explanation:

Analyze the chromosome diagram

The image shows chromosomes labeled "Chromosome 5". On the left, we see normal chromosomes with a short arm labeled \(p\) and a long arm labeled \(q\). On the far right, one chromosome is visibly shorter at the top, and it is labeled with the notation "5p-".

Interpret the notation and visual change

The notation "5p-" in genetics indicates a loss or deletion of material from the short arm (\(p\) arm) of chromosome 5. Visually, the top portion of the rightmost chromosome is missing compared to the normal chromosome 5 next to it.

Identify the mutation type

Since a segment of the chromosome is missing, this represents a deletion. This specific deletion on the short arm of chromosome 5 is associated with Cri-du-chat syndrome. Therefore, the correct mutation type represented is a deletion.

Answer:

• deletion (Correct answer)
• duplication
• insertion
• inversion
• substitution
