Explanation:

Chromosomal non - separation during meiosis is a form of chromosomal mutation. Gene mutation affects a single gene, not whole chromosomes. Trisomy is a specific type of chromosomal mutation (extra chromosome copy), but the general term for the error (chromosomal non - separation) is chromosomal mutation. Variation is a broad term and not specific to this error.

Answer:

chromosomal mutation
