Final answer:
The percentage of Allele A and the relative quantity of UVB are related through the concept of evolution. UVB radiation can cause mutations in DNA, which can affect the frequency of different alleles, including Allele A.
Step-by-step explanation:
The relationship between the percentage of Allele A and the relative quantity of UVB can be understood through the concept of evolution. A change in the frequency of Allele A over time would indicate evolution in the population. UVB radiation, which comes from the sun, is known to cause changes in DNA and can lead to mutations. These mutations can affect the frequency of different alleles in a population, including Allele A.
