Heterosis is typically used to increase vigour, size, growth rate, yield, etc. Uses can be in the following form.Increased yieldIncreased reproductive abilityIncrease in size and vigourBetter qualityGreater adaptabilityHeterosis is also increased by a rise in the rate of DNA reduplication, transcription, and translation, enzymatic activity, other regulatory systems, and the formation of hybrid protein molecules. However, in exceptional cases, the hybrid may be inferior to the weaker parent.
