A individual has a spontaneous single nucleotide polymorphism within an intron region of a transcriptional regulator. Such a mutation is likely to

B) be deleterious.
C) result in an altered transcript.
D) be neither advantageous not deleterious.
E) be inherited and increase or decrease in populations in a predictable fashion.

Mutations in intron regions often do not affect the final protein product because introns are non-coding regions that are removed during RNA splicing. Therefore, a single nucleotide polymorphism in an intron may not have any effect on the organism, making it neither advantageous nor deleterious.
