WebIn population genetics, scientists define the term evolution as a change in the allele's frequency in a population. Using the ABO blood type system as an example, the frequency of one of the alleles, IA, is the number of copies of that allele divided by all the copies of the ABO gene in the population. WebEvolution in terms of genetic can be defined as the change in allele frequency in a population over time from generation after generation. It’s an occurrence due to natural selection. When scientists try to determine whether a population is evolving genetically, …
