Final answer:
Chromosomal mutations are large-scale mutations that result from changes at the chromosome level, not the gene level. They can involve the deletion or duplication of large sections of a chromosome, inversions, or translocations, and can affect multiple genes, not just a single gene.
Step-by-step explanation:
No, the statement is false. Chromosomal mutations are large-scale mutations that result from changes at the chromosome level, not the gene level. Chromosomal mutations can involve the deletion or duplication of large sections of a chromosome, inversions, or translocations. These mutations can affect multiple genes, not just a single gene. So, chromosomal mutations do not result from changes in a single gene.
