What is the term for a change in the structure of a chromosome, such as deletion or translocation?

Explanation:
Structural changes to chromosomes are called chromosomal mutations. These involve alterations in the chromosome's physical structure, such as deleting a segment or rearranging parts through translocation. This is different from gene mutations, which are changes in the DNA sequence within a gene, and from point mutations, which are single-nucleotide changes. Aneuploidy refers to having an abnormal number of chromosomes, not a structural rearrangement. So deletions and translocations fall under chromosomal mutations because they change the chromosome’s architecture itself.
