Three different alleles (b1, b2, and b3) at the b locus exist in a hypothetical population of juniper trees. If the frequency of b1 is 0.4, what can be said about the frequency of b3?
A) It cannot be less than 0.4.
B) It is 0.6.
C) It is 0.4.
D) It is 0.
E) Insufficient information is given to answer the question.
