Answer:
The allele frequency of the dominant allele is 0.8 or 80%, and the allele frequency of the recessive allele is 0.2 or 20%.
Step-by-step explanation:
The allele frequency refers to the proportion of a particular allele within a population. To calculate the allele frequency of a population, we need to count the number of alleles of each type and divide by the total number of alleles in the population.
In this case, we have 20 dominant alleles and 5 recessive alleles, for a total of 25 alleles in the population.
To calculate the allele frequency of the dominant allele, we divide the number of dominant alleles by the total number of alleles:
allele frequency of the dominant allele = number of dominant alleles / total number of alleles
allele frequency of the dominant allele = 20 / 25
allele frequency of the dominant allele = 0.8 or 80%
To calculate the allele frequency of the recessive allele, we divide the number of recessive alleles by the total number of alleles:
allele frequency of the recessive allele = number of recessive alleles / total number of alleles
allele frequency of the recessive allele = 5 / 25
allele frequency of the recessive allele = 0.2 or 20%
Therefore, the allele frequency of the dominant allele is 0.8 or 80%, and the allele frequency of the recessive allele is 0.2 or 20%.
