Events of Sexual Reproduction

Sexual reproduction entails a complex life cycle. It comprises a set of events that are divided into the following three stages:

  1. Pre-fertilization: This stage covers the events before fertilization. The two events that take place during this stage are given below.
  2. Gametogenesis of gamete formation: In eukaryotes, diploid mother cells splits to produce haploid cells known as gametes, in a process called meiosis. This process involves the reunification of genetic materials.
  3. Transfer of gametes: Since the female gametes are immovable, male gametes are shifted for fertilization. In plants, this is attained by pollination. Unisexual animals transmit gametes through sexual intercourse.
  4. Fertilization: Two haploid gametes merge or integrate into one diploid cell to produce a zygote, which is the precursor to an embryo offspring, in the process called fertilization. This zygote consolidates the genetic material from both the gametes. It is also known as syngamy.
  5. Post-fertilization: Fertilization consequences in multiple cell divisions mitotically, without any alternates in the number of chromosomes, and forms a multicellular diploid phase that guides the zygote to develop into an embryo., the process is called embryogenesis.
