Aug 20, 2019 · A zygote is the first step in the creation of a completely new human, with a typically unique set of genes. If all goes well, the zygote will undergo cleavage, dividing and reproducing itself to create a small cluster of cells known as a blastocyst. The development of the blastocyst takes around five days from the moment of conception in humans.

In biological terms, human development entails growth from a one-celled zygote to an adult human being. Fertilisation occurs when the sperm cell successfully enters and fuses with an egg cell. The genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of prenatal development commences.

Within the world of Reproductive Biology, we can find many terms and concepts that people without specific health knowledge may confuse. This is the case of the words zygote, embryo and fetus, which definition and main differences will be explained hereunder.. It should be noted that these terms are used during the early stages of human development, known as Carnegie stages, which are based on.

A zygote is the union of the sperm cell and the egg cell. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo. If this goes well, the embryo becomes a fetus.
