occur when chromosomes fail to separate during meiosis.
○ duplication
○ inversion
○ translocation
○ nondisjunction

Explanation:

To solve this, we analyze each option:

• Duplication: Involves repeating a chromosome segment, not failure to separate.
• Inversion: Reverses a chromosome segment, not related to separation failure.
• Translocation: Exchange of chromosome segments between non - homologous chromosomes, not about separation during meiosis.
• Nondisjunction: By definition, it is the failure of chromosomes to separate during meiosis (or mitosis). This matches the description in the question.

Answer:

D. nondisjunction
