    reproductive cloning is to make whole organisms
    so includes nuclear transfer (dolly the sheep) and splitting embryos (in vitro fertilisation of the best egg and sperm from the parents with the desired traits then implanting them into surrogates once they have grown into an embryo)

    Non-reproductive
    making tissues and organs to replace faulty ones/ damaged

    hope this helps

    i can get all the other questions right but i can never get this right, i cant see where i am going wrong. can someone explain this to me?

    Two pure breeding strains of snapdragon, a garden plant, were obtained. Onestrain had red flowers and the other had white flowers. The two strains werecrossed yielding F1 plants all with pink flowers. The F1 were then interbred toproduce F2 plants with the following colours:

    red 62
    pink 131
    white 67

    The following hypothesis was proposed:Flower colour is controlled by a single gene with two codominant alleles.
    (b) Complete the genetic diagram to explain this cross.

    Use the following symbols to represent the alleles:Cr= red, Cw= white

    Parental phenotypes: red flowers x white flowers

    Parental genotypes: ................................ .... ................................ ........

    Gametes: ................................ .... ................................ ........

    F1 genotypes: ................................ ................................ ................................ .

    .F1 phenotypes: ................................ ................................ ................................

    Gametes: ................................ ................................ ................................ ........

    F2 genotypes: ................................ ................................ ................................ ..

    F2 phenotypes: ................................ ................................ ................................

    Expected F2 phenotypic ratio:.......................... ................................ ...............
