#Unit 8. Inheritance Biology
In mice Igf2 gene which encodes a protein called insulin like growth factor II (Igf2). Offspring inherit one Igf2 allele from their mother and one from their father The paternal copy of Igf2 is actively expressed in the fetus, but the maternal copy is not expressed. which of the following is correct about this gene?
a) this is an example of genomic imprinting and showing maternal imprinted
b) this is an example of genomic imprinting and showing paternal imprinted
c) mechanism of imprinting is due to the addition of methyl (CH3) groups to DNA nucleotides
d) mechanism of imprinting is due to changing the nucleotide sequences
