The Stages of Sexual Reproduction

Below, we will discuss the various stages of sexual reproduction.

1) Pre-fertilization

This stage involves the events prior to fertilization. Gamete formation (gametogenesis) and transfer of gamete are the two processes that take place during this stage. Gametes are sex cells which are haploid (23 chromosomes) in nature and are distinct in males and females.

Male gamete is called sperm whereas female gamete is called ovum or egg. In every organism, these gametes form within special structures. Since female gamete is immobile, male gametes need to be transferred for fertilization. In plants, this is pre-fertilization happens through pollination. Unisexual animals transfer gametes by sexual intercourse.

2) Fertilization

The process in which the haploid male and female gametes meet and fuse together to form a zygote is fertilization or syngamy. This can occur either outside the body known as External fertilization or inside the body known as Internal fertilization.

3) Post-fertilization

Fertilization results in diploid zygote formation. Eventually, the zygote divides mitotically and develops into an embryo. This process is called embryogenesis. During embryogenesis, cells differentiate and modify accordingly. Zygote development depends on the organism and its life cycle.

Animals are classified into oviparous and viviparous based on whether the zygote develops outside or inside the body respectively. In angiosperms, zygote develops into the ovary and ovary transforms into fruit while ovules develop into seeds.
