● The mitotic division called `color{Violet}"cleavag"`e starts as the `color{Violet}"zygote"` moves through the `color{Violet}"isthmus"` of the oviduct towards the uterus.
● It forms `color{Violet}"2, 4, 8, 16"` daughter cells called `color{Violet}"blastomeres"`.
● The embryo with `color{Violet}"8 to 16 blastomeres"` is called a `color{Violet}"morula"`.
● The `color{Violet}"morula"` continues to divide and transforms into `color{Violet}"blastocyst"` as it moves further into the uterus.
● The `color{Violet}"blastomeres"` in the blastocyst are arranged into an `color{Violet}"outer layer"` called `color{Violet}"trophoblast"` and an inner group of cells attached to trophoblast called the `color{Violet}"inner cell mass"`.
● The `color{Violet}"trophoblast layer"` then gets attached to the `color{Violet}"endometrium"` and the `color{Violet}"inner cell mass"` gets differentiated as the `color{Violet}"embryo"`.
● After attachment, the uterine cells `color{Violet}"divide rapidly"` and cover the `color{Violet}"blastocyst"`. As a result, the blastocyst becomes `color{Violet}"embedded"` `color{Violet}"in the endometrium"` of the uterus.
● This is called `color{Violet}"implantation"` and it leads to `color{Violet}"pregnancy"`.
