The fertilized egg is called a blastocyst during implantation. The blastocyst is a multicellular structure that forms from the fertilized egg as it develops and prepares for implantation in the uterine lining.
The four embryos are similar in that they are each cells at different early stages of development; they are all potential forms of a mature organism; and they have the same genetic material.
A zygote is the initial stage of a fertilized egg that forms when a sperm and egg merge. The zygote typically continues to divide and develop for about 5-7 days before implanting into the uterine lining and becoming an embryo.
Within two weeks of fertilization, the fertilized egg undergoes cleavage and forms a blastocyst, which implants into the uterine wall. The blastocyst begins to develop into different cell layers and structures that will eventually form the embryo. Hormonal changes also occur to support the pregnancy.
The group of approximately 100 cells that forms from a fertilized egg is called a blastocyst. It is the stage of development that precedes implantation in the uterus during early embryonic development.
an embryo
Fertilization occurs -> Zygote divides -> Placenta forms -> Gastrulation begins -> Heart forms.
in the ovary
cell division, after it caused the egg and sperm to fertilized
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.

Stem cells come from newly fertilized eggs.
