Natural selection is the most likely agent of evolution responsible for the decrease in the frequency of a recessive allele shown in the graph. This is because natural selection favors individuals with advantageous traits, so if the recessive allele leads to a disadvantageous trait, individuals with the dominant allele and advantageous trait will be selected for and the frequency of the recessive allele will decrease over time.
