Answer 1

The true statement is:
"Neutral mutations occur when a mutation in a DNA region results in the same sequence as the original."

Explanation: Neutral mutations do not change the organism’s phenotype or fitness. This often occurs with synonymous (silent) substitutions that do not alter the amino acid sequence, or mutations in nonfunctional regions. The other choices describe harmful or beneficial effects or merely location in a coding region, which do not define neutrality.
