Question

To solve this, we analyze each option:

• Translocation: Involves a chromosome segment breaking off and attaching to a non - homologous chromosome. This matches the description in the question.
• Deletion: Is the loss of a chromosome segment, not attaching to another chromosome.
• Inversion: Is when a chromosome segment breaks off, flips, and reattaches to the same chromosome, not another chromosome.
