Explanation

The order of events in pregnancy is as follows: Fertilization → Cleavage → Implantation Fertilization means the fusion of an egg and a sperm to form a zygote. Cleavage means the division of the zygote by mitosis. Implantation is when the blastocyst attaches itself to the endometrium lining in the uterus Gestation is the time period between fertilization and birth. The attachment of the embryo to the wall of the uterus is known as implantation. Implantation is a crucial step in the early stages of pregnancy during which the blastocyst, a structure formed from the dividing cells of the fertilized egg, attaches itself to the lining of the uterus.
