Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.

does not code for proteins and is same in all members of the population.

codes for proteins needed in cell cycle.

codes for proteins needed in cell cycle.

negative and inducible because repressor protein prevents transcription.

positive and inducible because it can be induced by lactose

negative and repressible because repressor protein prevents transcription

feedback inhibition because excess of $$\beta $$-galactosidase can switch off transcription
