This is a subject of active research. All the cells in the zygote are identical up to 8 cell stage. At the next division resulting in 16 cells formation it is called a morula. The zygote has totipotent cells meaning each cell has the ability to develop into full organism by itself if it separates from the zygote (this is how identical twins are born). ...
