Introduction
All human and animal embryos go through very similar stages of early development. See also Humans and Animal Embryology.
This page introduces a few of the concepts of development shared with all animals.
MeiosisIn the male and female in all animals (and plants) that reproduce sexually to form an embryo, these very first cells form by meiosis. Meiosis a reductive form of cell division that only occurs in the egg (oocyte) and sperm (spermatozoa) and allows new genetic combinations of offspring to be generated. Meiosis has 2 key components:
Mitosis
