Introduction:
The frequency of an allele is the proportion of that allele in a population. In this case, the frequency of the red flower allele is 0.8, which means that 80% of the population has the red flower allele.

Calculation:
To determine the population of white flowered plants, we need to first determine the frequency of the white flower allele. Since there are only two alleles in this population (red and white), the frequency of the white flower allele can be calculated by subtracting the frequency of the red flower allele from 1.

Frequency of white flower allele = 1 - frequency of red flower allele
Frequency of white flower allele = 1 - 0.8
Frequency of white flower allele = 0.2

This means that 20% of the population has the white flower allele.

To determine the actual number of white flowered plants in the population, we need to know the total population size. Let's say that the total population size is 1000.

Number of white flowered plants = frequency of white flower allele x total population size
Number of white flowered plants = 0.2 x 1000
Number of white flowered plants = 200

Therefore, in a population of 1000 wild flowers with a red flower allele frequency of 0.8, there are 200 white flowered plants.

Conclusion:
The population of white flowered plants can be determined by subtracting the frequency of the red flower allele from 1 to get the frequency of the white flower allele. Then, the actual number of white flowered plants can be calculated by multiplying the frequency of the white flower allele by the total population size.
