Question

select the correct answer.

which statement about somatic mutations is true?

they exist in all the cells of the body.
they are acquired through exposure to mutagens.
they are inherited via sperm and egg cells.
they are passed on to offspring.

Explanation:

Define somatic mutations

Somatic mutations occur in non-reproductive cells after fertilization.

Analyze cell distribution

These mutations affect only descendants of the mutated cell.
They do not exist in all body cells.

Evaluate environmental causes

Somatic mutations often arise from environmental mutagens like UV.
This makes acquisition through mutagens a true statement.

Assess heritability

Somatic cells do not form sperm or eggs.
Thus, they cannot be passed to offspring.

Answer:

• They exist in all the cells of the body.
• They are acquired through exposure to mutagens. (Correct answer)
• They are inherited via sperm and egg cells.
• They are passed on to offspring.
