The implantation process involves the following steps :
(I) The morula continues to divide and transforms into blastocyst as it moves further into the uterus.
(II) The uterine cells divide rapidly and the blastocyst gets covered by them.
(III) Morula is formed.
(IV)As the zygote moves through the isthmus of the oviduct towards the uterus, it undergoes mitotic division and forms 2, 4, 8, 16 daughter cells called blastomeres.
