Allele frequency can be described as the percentage or ratio for the existence of a particular allele in a population. Allele frequency determines which allele is present more abundantly in a population and which allele is not significantly present in the population. The allele frequency determines the genetic diversity which will be present in a population. The alleles which code for traits that make an organism more adaptable to a particular environment will have an increased allele frequency.
Three of the boxes contain an Upper case F, therefore 75% of the boxes have an Upper case F. It's like quarters, if you have 4 quarters you have 100 cents, if you have 3 you have 75 cents, if you have 2 you have 50 cents, and if you have 1 you have 25 cents.
