- Gametes (sperm and ova) are haploid cells.
The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes)
- The steps of fertilization in humans always involve the joining of an egg and sperm.
- In natural conception, the male sperm fertilizes the female egg inside the woman's body.
- While many think fertilization occurs in the ovary, it actually takes place in the fallopian tube just outside the ovary.
