Some steps involved in the process of fertilization: 1. zygote. 2.morula 3.oocyte 4.fertilization 5. cleavage 6.blastocyst. the order in which the steps numbered above occur in the process of fertilization is.

Step 1: ovulation

A secondary oocyte is released from the ovary and swept into the oviduct

Step 2: fertilization

A single sperm penetrates the secondary oocyte. Eventually, the sperm and egg nuclei will fuse, resulting in a fertilized egg, or zygote.

Step 3: cleavage

The zygote soon undergoes rapid mitotic cell divisions as it moves along the oviduct toward the uterus, becoming a pre-embryo that consists of two cells, then four cells, then eight cells, and so on.

Step 4: morula

By day 4, successive divisions produce a morula, a solid ball of cells that enters the uterus

Strep 5:blastocyst

By day 6, the pre-embryo becomes a blastocyst, a hallow ball of cells with a fluid-filled cavity. The blastocyst has freed itself from the zona pellucida and can increase in size.

Step 6: implantation

The blastocyst attaches to the uterine lining (endometrium) and begins to digest its way inward. The cells of the inner cells mass begin to form primary germ layers.

Zygote

A fertilized ovum contains genetic material from the mother and father (23 chromosomes each)
