Gamete production and fertilisationFertilisation

Gametes are reproductive cells. Male gametes are called sperm. Female gametes are called ova. Fertilisation takes place in the oviduct when the nucleus of a sperm fuses with the nucleus of an ovum. These two haploid cells produce a diploid zygote.

Fertilisation

Mature ova are released from the ovary into the oviduct where they may be fertilised by sperm to form a zygote.

Fertilisation is the fusion of the of a male with the nucleus of a female gamete, producing a new cell called a . This then matures into an embryo.

Egg (23 chromosomes) combines with sperm (23 chromosomes).  Fertilisation occurs creating a zygote with 46 chromosomes in 23 pairs. This matures into embryo with 46 chromosomes in 23 pairs.

In humans, fertilisation happens inside the woman鈥檚 body. This is a process called internal fertilisation.
