Three different alleles (c1, c2, and c3) at the c locus exist in a hypothetical population of juniper trees.If the frequency of c1 is 0.3, what can be said about the frequency of c2?
A) It cannot be less than 0.3.
B) It cannot be greater than 0.3.
C) It is 0.7.
D) It is 0.
E) More information is required to answer this question.

The frequency of c2 cannot be determined with the information given because we also need to know the frequency of c3 to calculate the frequency of c2. The sum of the frequencies of all alleles at a locus must equal 1, but without the frequency of the third allele, c3, we cannot determine the frequency of c2.
