Point mutations in noncoding regions of dna result in

Neutral Variation

Explanation

Point mutations in noncoding regions of DNA result in neutral variation. The alleles which neither considerably sum to nor exceedingly lower from body consistency. It is the accumulation of such alleles located within a community that can be explained as expressing neutral variation. Neutral Variation implies in various alleles that are existing at an assigned genetic locus because those alleles are not distinct by natural selection.
