The correct answer is: C. a change that is inherited.
A mutation is a permanent change in the genetic material (DNA) of an organism. Mutations can be caused by errors in DNA replication, exposure to radiation or chemicals, or viruses. Mutations can be beneficial, harmful, or neutral. Beneficial mutations can help an organism survive and reproduce, while harmful mutations can cause disease or death. Neutral mutations have no effect on the organism.
Mutations can be inherited if they occur in the germ cells (egg or sperm cells). These mutations can then be passed on to the offspring. Mutations that occur in somatic cells (all other cells in the body) are not inherited.
Mutations are an important source of genetic variation. Genetic variation is the raw material for evolution. Without mutations, evolution would not be possible.
Here is a brief explanation of each option:
- Option A: A factor responsible for plant growth. This is not correct because mutations can affect any organism, not just plants.
- Option B: A change which affects the offspring of F2 generation only. This is not correct because mutations can affect any generation, not just the F2 generation.
- Option C: A change that is inherited. This is the correct answer because mutations can be passed on to the offspring.
- Option D: A change which affects the parents. This is not correct because mutations can affect any organism, not just the parents.
