Answer:

The correct answer is d) genomic imprinting.

Explanation:

Genomic imprinting is a biological process by which specific modifications in the germ line that produce differences in the expression of the genetic material that is biochemically marked indicating its parental origin. The Prader-Willi syndrome is one of the best known and most studied examples in relation to pathologies produced by genomic imprinting.
