Which of the following statements about gene mutations is true?
A
Gene mutations can be beneficial, neutral, or harmful.
B
Gene mutations always result in harmful effects.
C
Gene mutations occur only in somatic cells.
D
Gene mutations are always inherited from parents.
Verified step by step guidance1
Understand that gene mutations are changes in the nucleotide sequence of DNA, which can occur in any cell of the body.
Recognize that mutations can have different effects: they can be beneficial, neutral, or harmful, depending on the context and environment.
Consider that mutations can occur in both somatic cells (non-reproductive cells) and germ cells (reproductive cells), but only mutations in germ cells can be inherited by offspring.
Acknowledge that not all mutations are inherited; some occur spontaneously in somatic cells and are not passed to the next generation.
Conclude that the statement 'Gene mutations can be beneficial, neutral, or harmful' is true, as it accurately reflects the diverse potential impacts of mutations.
