The correct answer is Zygote.

Key Points

  • The fusion of the male gamete and female gamete is called fertilization.
    • Fertilization of gametes results in the formation of a zygote.
  • Gamete formation: These are cells used during sexual production. The male gamete is sperm while the female gamete is the egg or ova.
  • Fertilization: This is the process where the male and female gametes fuse to form a single cell called a zygote.
  • Zygote: This is the combination of the parent gene(male and female gene) formed during fertilization.
    • It contains the necessary genetic information to form a new human being.
  • Embryo: This is the early stage of development of the new individual.
  • The correct sequence of events is during reproduction in human beings.

    Gamete formation → Fertilization → Zygote → Embryo
