  • Transformation – It refers to the bacterial cells taking up the DNA from the environment.
  • Heterosis –  The phenomenon known as heterosis occurs when two or more species cross or hybridize.
  • The hybrids of the F1 generation, which are crossed between two unrelated individuals are superior to their parents in different terms. They outperform their parents in terms of growth, size, fecundity, function, yield, or other characteristics.
  • Metamorphosis – It refers to a structural change in the organism.
