Cloning and Selective Breeding

Cloning and selective breeding

Clones ar genetic whollyy identical individuals. nearly plants beat clones naturally by asexual reproduction. For example:
wanderer plants rear bracing plants, called plantlets, on their stems
Potato plants produce tubers (the develop we eat), which can grow new grow and shoots
Strawberry plants grow stems called runners, which have plantlets on them

Cuttings

Plants can be cloned artificially development tissue culture.

The simplest way to clone a plant involves pickings a misfortuneting. A branch from the parent plant is cut off, its lower leaves removed and the stem planted in come apart compost. Plant hormones are often used to encourage new roots to develop. The cutting is usually covered in a clear plastic bag at this stage to persist in it moist and warm. After a few weeks, new roots develop and a new plant is produced. The method is simple enough for most gardeners to do successfully.

Advantages and disadvantages

Cloning allows growers to mass produce plants that may be difficult to grow from seed. All the plants are genetically identical, which is useful because you can be sure of their characteristics. On the other hand, the lack of genetic variation means that if the plants locomote exposed to disease or to changes in environmental conditions, all of them will be affected.





Uses of animal clone

Possible uses of animal cloning include:
* Mass producing animals with desirable characteristics, such as overawe that produce a lot of milk
* Producing animals that have been genetically engineered to give up gaykind products, such as insulin or organs for transplant
Producing human embryos to supply stem cells for therapy

However, there are ethical dilemmas concerning human cloning
The cloning process of Dolly the sheep

Main steps

* Removing the nucleus from an clump cell
* Putting the nucleus from an udder cell into the egg cell
* cock-a-hoop the egg cell an electric shock to make it divide
* Implanting the embryo...If you wishing to get a full essay, order it on our website: Ordercustompaper.com
