Because chromosome mutations can result in improper child development, their effects are frequently far more severe than those of gene mutations. The best choice is B.
A mutation is a change to the DNA sequence of an organism. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all result in mutations. When a DNA gene is disrupted or altered in such a way that the genetic notification carried out by that gene is altered, mutations occur. A mutagen is a substance that permanently modifies the physical components of a DNA gene, changing the genetic information. Chromosome structural changes have the potential to impair system growth, development, and operation.
