What is the role of a 'reporter gene' in the production of transgenic animals?
It encodes the protein of interest.
It helps identify cells that have successfully incorporated the transgene.
It promotes the integration of the transgene into the host genome.
It silences the expression of other genes.

A transgenic animal is created by inserting a gene for enhanced muscle growth into its genome. However, the resulting offspring show a variety of phenotypes, some with significantly enhanced muscle growth, others with moderate enhancement, and some with no change at all. Which phenomenon is MOST likely responsible for this phenotypic variation?
Incomplete penetrance of the transgene
Pleiotropic effects of the transgene
Variable transgene copy number and integration sites
Epigenetic silencing of the transgene in some individuals
