Origin of Zygote. The term âzygoteâ means âyoked togetherâ in Greek, reflecting the fact that the cell contains genetic material from both parents, brought together for the first time to create a cell with a full set of genes. 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.
