Quizplus · Accepted Answer

At the point of fertilization, the sperm cell and the ovum combine to form a single cell called a zygote. This zygote will eventually develop into an embryo and later a fetus. A chromosome refers to a single piece of DNA that carries genetic information, and an embryo and fetus are stages of development after the formation of the zygote.
