Question
A mouse that is homozygous for the wild-type Igf2 allele is
Normal in size
Dwarf
Larger in size
None of the above
Normal in size
Dwarf
Larger in size
None of the above
Hint:
Normal in size
The correct answer is: Normal in size
IGF2 gene of mouse encodes for insulin like growth factor II. A mouse that carries two normal wild type alleles of this gene is normal in size, whereas a mouse that carries two mutant alleles is dwarf.
