Mutations and polymorphisms are both changes in a DNA sequence,but polymorphisms are more common because
A)they less severely affect the phenotype,so that individuals can reproduce and transmit them.
B)more people have them.
C)mutations are always lethal.
D)mutations refer to a real situation,whereas a polymorphism is an idealized state hypothesized by biologists to explain genetic change.
