WebJun 8, 2024 · The theory of evolution gives us a unifying theory to explain the similarities and differences within life’s organisms and processes. Populations (or gene pools ) evolve as gene frequencies change; individual organisms cannot evolve. Variation in populations is determined by the genes present in the population’s gene pool, which may be ... Web1. The melanic (black) phenotype had two possible genotypes. 2.
