Cloning and selective breeding Clones ar genic whollyy uniform individuals. nearly botanys beat clones naturally by asexual reproduction. For typeface: wanderer jells rear bracing plants, called plantlets, on their stems Potato plants expose tubers (the develop we eat), which force out grow young grow and shoots hemangioma simplex plants grow stems called runners, which have plantlets on them Cuttings Plants can be cloned by artificial means 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 apply to encourage new roots to develop. The cutting is usually cover 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. Adv antages and disadvantages Cloning allows growers to mass produce plants that may be demanding 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 living organism clone Possible uses of animal cloning include: * push-down storage 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, suc h as insulin or organs for transplant Produ! cing forgiving embryos to supply stem cellphones for therapy However, there are ethical dilemmas concerning kind cloning The cloning process of Dolly the sheep Main steps * Removing the lens 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: OrderEssay.net
