    Reproduction does not always require two parents, The type of reproduction in animals that occur with a single parent and produces offspring by cell division or splitting of one cell into two is called

    asexual reproduction

  • 2

    Through the process of mitosis, unicellular of one-celled organisms, such as amoeba or paramecium, can reproduce an exact copy of the parent in an asexual process called

    fission

  • 3

    asexual reproduction occurs through many forms to perpetuate their kind. Cnidarians such as hydras reproduce asexually by

    budding

  • 4

    The new outgrowth can become an independent animal or may remain attached to the parent forming a colony. Annelids, such asthe earthworm, can also reproduce by regenerating parts through

    fragmentation

  • 5

    faster is?

    asexual

  • 6

    slower is?

    sexual

  • 7

    Higher forms of animals reproduce through a process involving sex cells of gametes produced by the parents.

    sexual reproduction

  • 8

    Animals produce their sex cells or gametes through their reproductive organs known as

    gonads

  • 9

    what are the 2 types of fertilization?

    external and oviparous organism

  • 10

    In many organisms, particularly aquatic animals, sexual reproduction occurs outside of the body

    external

  • 11

    Then the male comes along and sprays the eggs with sperm cell and fertilization takes place. Animals that practice external fertilization

    oviparous

  • 12

    The exchange of waste between the blood of the mother and the embryo also takes place here, The placental mammals are viviparous, which means the young develops inside the mother's body

    viviparous

  • 13

    is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete without combining with another gamete

    parthegonesis

  • 14

    a form of asexual reproduction consisting of the spontaneous transverse segmentation of the body.

    transvere fission

    artificial selection:

  • 20

    Three tvpes of artificial selection:
