polymorphism is define existence of two or more form of same species within same population at the same time and place .polymorphism either balanced or transient depending upon type of natural selection  which of the following reason for balanced genetic polymorphism

a. each morph has selective advantage at equal intensity

b. non of the morph has selective advantage over other

c. heterzygote superiority

A very common isotope substitution is when hydrogen is replaced by deuterium. This is known as a deuterium effect and is expressed by the ratio kH/kD (as explained above). Normal KIEs for the deuterium effect
