Zygote
Your baby is scientifically known as a zygote for about 5-7 days after fertilisation. A zygote is best explained as the cell that results from the fusion of two gametes. In the case of your baby, the gametes are your partner’s sperm and your egg.
Zygotes carry the genetic information which will determine what your baby looks like. Half of this information comes from the father and half of it comes from the mother. After fertilisation the zygote undergoes mitosis until it develops enough cells to be considered an embryo.
