Question 24

Consider the genes IGF2 and H19 and the imprinting control region ICR)between them.If the paternal ICR region was mutated in such a way that it could not be methylated but the maternal ICR was not mutated,how would that effect growth? In your explanation describe the expression of IGF2 and H19 from both the maternal and paternal alleles.
