After two gametes fuse to form a fertilized egg, it starts to divide into more cells. In humans, this ball of cells becomes implanted in the wall of the uterus.
Fertilization restores diploid cells.
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
It is not complete.
5 to 7 days
the embryo attaches the mother
Fertilization restores diploid cells.
Cross-Fertilization!
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.

External fertilization
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
The process that forms a zygote is called fertilization.
Where sex cells are produced: meiosis Where sex cells unite: fertilization
Sperm and egg cells are the two cells involved in fertilization of animals and humans.
