In human beings, the correct sequence of events during reproduction is:
  • Gamete formation, fertilization, zygote, embryo.
  • B
    Embryo, zygote, fertilization, gamete formation.
  • C
    Fertilization, gamete formation, embryo, zygote.
  • D
    Gamete formation, fertilization, embryo, zygote.

Answer

Correct option: A.
Gamete formation, fertilization, zygote, embryo.
In human beings, the process of reproduction starts by the formation of male and female gametes respectively in the male and female reproductive systems. This is followed by the fusion of these gametes inside the female body, a process called fertilization. The fertilized product of this process is termed as a zygote. The fusion forms a zygote, which divides repeatedly to form the embryo. The embryo gets implanted in female uterus for further development to form foetus. Thus, the correct sequence is gamete formation, fertilization, zygote and embryo. Hence, your answer should be option $(a)$.
