Question

3/6
Select all the statements that apply to mutations:
Select all correct options
Mutations are random
Mutations are a source of genetic variation
Mutations are always bad
Mutations are changes in DNA sequences
ALL mutations are passed down to the offspring

Answer 1

The following statements are correct regarding mutations:

1. **Mutations are random** - Mutations occur spontaneously and can happen due to various factors, often at random.

2. **Mutations are a source of genetic variation** - Mutations provide new alleles and thus contribute to the genetic diversity within a population.

3. **Mutations are changes in DNA sequences** - By definition, mutations refer to alterations in the DNA sequence.

The incorrect statements are:

- **Mutations are always bad** - This is not true; some mutations can be beneficial, neutral, or harmful depending on the context.

- **ALL mutations are passed down to the offspring** - This is also incorrect; only mutations that occur in germ cells (sperm and eggs) can be inherited by the next generation, while mutations in somatic (non-reproductive) cells are not passed on.

So the correct options are:
- Mutations are random
- Mutations are a source of genetic variation
- Mutations are changes in DNA sequences
