Fertilization is significant as it ensures diploidy in organisms through the fusion of haploid gametes, provides a new genetic makeup in the zygote, and increases the metabolic and protein synthesis rates in the egg which causes genetic variation and aids evolution.

8. SIGNIFICANCE
• 1)Fertilization ensures diploid of the organism by fusion
of haploid male and female gametes.
• 2) Fertilizationprovides new genetic constitution to the
zygote 3) Fertilization process increases the metabolic
activities and the rate of protein synthesis of the egg.
• 4)It causes genetic variation and help in evolution.
