The diagram below represents human chromosome 2 of one person. The gray region of the chromosome represents the gene that codes for the light chain of the myosin protein (the drawing is not to scale). Would a mutation to this chromosome always result in a visible change to this diagram?

Question

A mutation to this chromosome would not always result in a visible change to this diagram as there are many possible types of mutations (e.g. point mutations, insertions, deletions) that could occur within the coding region of the gene or outside of it, and not all mutations necessarily affect the structure or length of the chromosome. Additionally, the diagram is not drawn to scale and does not show all possible variations in the chromosome structure or gene expression.
