Zygotes are usually produced by a fertilization between two haploid cells—an ovum and a sperm cell, which combine to form the single diploid cell. Such zygotes contain DNA from both the parents, and this provides all the genetic information necessary to form a new individual. After fertilization has taken place the zygote travels down the fallopian tube, dividing to form more cells without the zygote actually increasing in size.
