Which statement best describes the fertilized ovum at the time of implantation?

Question

Quizplus · Accepted Answer

The fertilized ovum, or zygote, undergoes several rounds of mitotic division as it travels down the fallopian tube towards the uterus, where it implants. This process, known as cleavage, results in an increase in cell number without an increase in overall size, forming a multicellular structure. Meiosis is the process of cell division that results in gametes with half the number of chromosomes of the parent cell and does not occur in the zygote after fertilization. Apoptosis is programmed cell death, which is not characteristic of early embryonic development at the stage of implantation.
