Three different alleles (c1, c2, and c3) at the c locus exist in a hypothetical population of juniper trees. If the frequency of
prisoha [69]

Answer:

d

Explanation:

When considering the frequency of the potential alleles of a gene in a population, the total must add up to 1. Think of it like percentages. an allele frequency of 0.3 means 30% of the population carry it (out of a possible 100%).

We know that the frequency of c1 is 0.3. Lets take each option and see if it can be true

a) cannot be less than 0.3.  - false. It <em>could </em>be less than 0.3. For example, it could be 0.1, meaning the frequency of allele c3 would be 0.6 (because 0.3 + 0.1 + 0.6 = 1)

b) cannot be greater than 0.3. - false. It <em>could </em>be greater than 0.3. For example, it could be 0.5, meaning the frequency of allele c3 would have to be 0.2 (because 0.3 + 0.5 + 0.2 = 1)

c) is 0.7.  - false. It <em>can't </em>be 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)

d) cannot be greater than 0.7. - true. It <em>cannot </em>be greater than 0.7, because  that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
