Question

Quizplus · Accepted Answer

The correct term for the new cell created at fertilization is a zygote. It is formed when the sperm and egg unite, and contains the complete set of chromosomes (half from the mother and half from the father) that will ultimately determine the genetic make-up of the developing fetus. Embryo, genome, and blastocyst are also stages of prenatal development, but they refer to different stages of development after the zygote has undergone some division and differentiation.
