Identical twins
The cell that forms when an egg and a sperm joins is called a zygote.
Cytokinesis is when the cytoplasm divides two daughter cells and forms the same number of chromosomes as a parent
The centriole is the part of the cell that goes to the end of each cell during prophase and forms spindal fibers.A centriol is what divides cells and is only in animal cells
single cell divides into two cell and chromosomes are mulilied
Through studying embryos, scientists have found that vertebrate animals seem to have a common design, even though their adult forms are different. Arm buds on different species, for example, look the same early on during embryonic development, yet they will develop into very different forms in the adult (a flipper, an arm, a wing, etc).

I searched this in google:A twin is one of two offspring produced in the same pregnancy. Twins can either be monozygotic, meaning that they develop from one zygote that splits and forms two embryos, or dizygotic, meaning that they develop from two eggs, each fertilized by separate sperm cells.That is gemellology.
Blastocyst
This is called the zygote. As it divides, it forms the embryo.
Blastocyst
Cell division
This occurs when a eukaryotic cell divides in mitosis or meiosis. The cell plate forms during telophase and is what divides the cytoplasm for the 2 daughter cells.
Stem cells come from newly fertilized eggs.
