B14.5-6 Animal Cloning Flashcards
Explain the steps of embryo splitting/ transplants
Embryo is collected
Embryo allows to divide and split apart
2 embryo’s placed in surrogate mothers
2 identical offspring are born
What is the problem with embryo splitting ?
We cannot be certain that the offspring will have the characteristics that we want
This is due to us starting with sperm and an egg
How can we overcome the problems of embryo splitting ?
Adult cell cloning
Explain the steps of adult cell cloning
Nucleus removed from a body cell is extracted
Nucleus placed in empty egg cell. Electric shock is used to stimulate division
Embryo placed in surrogate mother
What are the pros of cloning
Can replicate ideal traits exactly as we are cloning an adult
Plant— cheap and easy to do
Preserving endangered species
What are the cons of cloning
1 Reduces gene pool and genetic variation
2. Animal cloning—- expensive
3. Adult cell cloning- low success rate
4. Embryo splitting— offspring unknown until birth
5. Ethic morality and religious belief
6. Cuttings damage plant
7. Tissue culture- condition must be aseptic
