What is the frequency of the white allele (cw) in this population?

Considering that the population of white flowers in which the frequency of red allele CR is p = 0.7, then the frequency of the white allele (CW) in the population will be p=0.3. This is because the population contains white allele and the red allele therefore the two should add up to 1. Allele is the alternative form of a gene that codes for a specific trait.
