Cloning is the process used to create an exact genetic copy of an organism while selective breeding is the process used to produce particular characteristics and traits in organisms. Some types of cloning can occur naturally, but selective breeding only occurs when humans intervene.Know More
Cloning happens through asexual reproduction. However, natural clones can occur in humans and other mammals. Identical twins occur when a fertilized egg splits and creates embryos with almost identical DNA.
There are three different types of cloning. Gene cloning creates copies of genes or DNA, therapeutic cloning creates embryonic stem cells, and reproductive cloning creates copies of whole animals.
While cloning only uses asexual reproduction, selective breeding also uses sexual reproduction. The desired characteristics are chosen, and a male and a female who exhibit those characteristics are bred together.
Plant breeders strive to produce plants with desirable characteristics such as high growth rate or resistance to disease. This is done by crossing two members with dominant alleles for particular genes.
Excessive selective breeding can cause the removal of particular genes from the gene pool altogether. Creating organisms exclusively with more desirable genes can cause the less desirable genes to phase out completely. This is not a risk in the cloning process.Learn more about Molecular Biology & DNA
Selective breeding is the process of choosing a breeding stock of an animal based on specific traits that a breeder wants to reproduce in the offspring. There are two types of selective breeding or artificial selection.Full Answer >
Plants and flowers reproduce in two distinct ways, either through the process of pollination, in which the genetic material of two plants are combined to create an offspring, or through asexual reproduction, in which one plant makes an exact genetic copy of itself. Flowering plants reproduce almost exclusively through pollination, while other types of plants may reproduce by either method depending on the plant's reproductive system.Full Answer >
Selective breeding poses several risks for dogs, including raising the risk of developing heart problems, kidney disease, heating prostration, the inability to cool the body, hearing and vision problems and blood disorders. Selective breeding may also create emotional or neurological problems. Some breeds, such as Bull Terriers, have a tendency to chase their tails incessantly, while Scottish Terriers may lose muscular control when they are excited.Full Answer >
Selective breeding, also called artificial selection, is carried out by mating animals or crossing plants with desired characteristics or traits to produce offspring in which those traits are more dominant, according to Encyclopedia Britannica. The breeder attempts to isolate the genes responsible for the desired trait in subsequent generations so the quality becomes more pronounced and fixed.Full Answer >
