  2. Zygote - Wikipedia

    en.wikipedia.org/wiki/Zygote

    The zygote is the earliest pp developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. The formation of a totipotent zygote with the potential to produce a whole organism depends on epigenetic reprogramming.

  3. Human fertilization - Wikipedia

    en.wikipedia.org/wiki/Human_fertilization

    Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [1] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century. [2]

  4. Human embryonic development - Wikipedia

    en.wikipedia.org/wiki/Human_embryonic_development

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

  6. Animal embryonic development - Wikipedia

    en.wikipedia.org/wiki/Animal_embryonic_development

    The fertilized egg cell is known as the zygote. [2] [5] To prevent more than one sperm fertilizing the egg , fast block and slow block to polyspermy are used. Fast block, the membrane potential rapidly depolarizing and then returning to normal, happens immediately after an egg is fertilized by a single sperm.

  7. Egg - Wikipedia

    en.wikipedia.org/wiki/Egg

    An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches.

  8. Human reproduction - Wikipedia

    en.wikipedia.org/wiki/Human_reproduction

    Only 1 in 14 million of the ejaculated sperm will reach the fallopian tube. The egg simultaneously moves through the fallopian tube away from the ovary. One of the sperm encounters, penetrates and fertilizes the ovum, creating a zygote. Upon fertilization and implantation, gestation of the fetus then occurs within the uterus. [11] [12] [13] [14]
