1. Humans carry out sexual reproduction.

2. During intercourse, sperms from the male enters into the body of the female.

3. These sperms can ppotentially fertilise the egg or the ovum from the female.

4. After a successful fertilisation, a zygote is formed, which is initially just a diploid cell.

5. There are multiple stages of the growth of this zygote, which later matures to form a foetus.
