Natural cloning:
- Clones are genetically identical organisms or cells
- They are produced by asexual reproduction where the nucleus is divided by mitosis( creates 2 identical copies of DNA separated into 2 genetically identical cells)
- Any individual which reproduces asexually will inevitably produce a clone of itsel
Advantages of natural cloning:
- If conditions for growth are good for parent they will be equally good for the offspring
- Cloning is rapid- populations increase rapidly in order to take advanatage of suitable environmental conditions
- Reproduction can be carried out even if there is only one parent and sexual reproduction is not possible
Disadvantages of natural cloning:
- Offpsing may be overcrowed
- No genetic diversity
- Population will show little variations
- Selection is not possible
- Population becomes susceptible if the environment becomes less advantageous
Plant cloning by vegetation propagation:
- Differenciation of plant cells is not as complete as in animals
- This is because:This means that plants are able to reproduce by cloning
- Plant contain cells that retain ability to divide and differenciate into range of type of cell
Runners, Stolons and suckers:
- Plants that grow horizontal stems can form roots at certain points
- These stems are called Runners and Stolens as they grow on the surface of the ground
- Those which grow underground are known as Rhizomes (thickened over-wintering…
