What is the Stable Presence of More Than One Allele

Question

What is the stable presence of more than one allele for a particular gene in a population called?
A) balanced polymorphism
B) mixed gene pool
C) mutation pressure
D) genetic drift

Accepted Answer

Balanced polymorphism refers to the situation where two or more alleles persist in a population because they each confer some selective advantage that allows them to be maintained in a stable frequency. This concept is key in understanding how genetic diversity is preserved within populations.
