All of the following would be visible on a karyotype except

Step 1: Define the Problem

Identify what a karyotype displays and determine which elements are not visible on it.

Step 2: Break Down the Problem

1. Understand what a karyotype is.
2. List the components typically visible on a karyotype.
3. Identify what is not visible on a karyotype.

Step 3: Apply Relevant Concepts

• A karyotype is an image of an individual's chromosomes, organized in pairs.
• It shows the number, size, and shape of chromosomes.
• It can reveal chromosomal abnormalities, such as extra chromosomes or missing chromosomes.

Step 4: Analysis, Verify and Summarize

• Visible on a Karyotype: Chromosome number, structure, and any large-scale chromosomal abnormalities.
• Not Visible on a Karyotype: Gene mutations, small DNA sequence changes, or specific gene locations.

Final Answer

Gene mutations or small DNA sequence changes would not be visible on a karyotype.
