Question

Quizplus · Accepted Answer

Fertilization is the process of the fusion of a secondary oocyte (released from the ovary during ovulation) and a sperm cell, which results in the formation of a zygote. This is the initial step in the development of a new individual. Option A is incorrect as the primary oocyte is not capable of fertilization. Option B is incorrect as the secondary oocyte needs to be fertilized first before it can travel down the uterine tube. Option C is incorrect as it only describes a part of the journey of the oocyte. Option E is incorrect as this refers to implantation, which is a later stage in the development of the zygote.
