In contrast to mutations in coding regions introns mutations

In contrast to mutations in coding regions (introns), mutations in regulatory regions (non-coding) regions of the genome:

a. are less likely to result in the death of the individual

b. are more likely to result in the death of the individual

c. are less likely to result in the formation of monsters and/or superheroes.

Solution

The answer is b.
Regulatory region is a sequence which is capable of increasing or decreasing the expression of a particular genes. Since they don\'t necessarily affect the product (rather than rate of production of the product), they b. are more likely to result in the death of the individual
