The gametes are the sex cells
Sperm and ova are needed for human reproduction
A sperm cell carries all the genetic information (DNA) of the parents
A zygote carries half of the genetic information (DNA)
Fertilazation happens when the spern and ovam meet. The spem swim out of the penus and into the
vaginia. The sperms swim throgh the servix into the uturus. Half the sperm swimm up the left ovaduct
and the other half swimm up the right oviduct. Each mounth an ovom is releassed from an ovary. If a
sperm meets the ovum in the oviduct then it can join togother to form a zygot.
