Examples of selective breeding in a sentence, how to use it. usually this is practiced on by plants and animals. Selective breeding uses artificial selection to direct the genetic transfer of desirable traits. 5. Lesson Overview Meeting Ecological Challenges Selective Breeding The differences among breeds of dogs are great. 2. Humans use selective breeding to produce animals with certain desired traits. if(!window.jQuery) alert("The important jQuery library is not properly loaded in your site. If you are still not sure what to do you can contact us for help. This process is a example of selective breeding. Not only can the lack of genetic diversity within the gene pool lead to hereditary health problems, dogs that are bred with deliberately accentuated physical features can suffer from their unnatural physical form. mode: 'thumbnails-a', Selective breeding of domesticated animals has also resulted in the generation of diverse breeds of offspring. Selective breeding in plants started the selection of fruits and vegetables for qualities such as large size and sweetness unconsciously; the seeds of plants with the desirable qualities would have been given the chance to germinate through human consumption and cultivated within their latrines (toilets). }(document, 'script', 'facebook-jssdk')); Page 2 A. Where did these differences come from? _taboola.push({ 1. Artificial selection and selective breeding, on the other hand, are a deliberate attempt to breed animals for particular characteristics, such as a certain color of fur or a particular skin pattern. Selective breeding is a process that usually takes time. The term ‘artificial selection’ was first coined by Charles Darwin in his book On the Origin of Species to describe how humans had mirrored the process of natural selection through selective breeding. Laboratory-based genetic modification is relatively new when you consider the centuries of selective breeding that precedes it. As opposed to natural selection, selective breeding focuses on traits which will benefit humans. window._taboola = window._taboola || []; Over time, other favorable qualities, such as oil content, seedlessness, and fleshy texture were all altered, leaving many human-cultivated fruit and vegetables unrecognizable against their wild counterparts. Dogs were first bred from a common ancestor of the gray wolf (Canis Lupus), which was domesticated by humans with whom it lived in close proximity. The selective breeding that created the hundreds of modern dog breeds has put purebred dogs at risk for a large number of health problems, affecting both body and behavior. Home‎ > ‎Methods of selective breeding‎ > ‎ Examples. 86 examples: Those that do produce fine wool include products of selective breeding… Selective breeding, which takes advantage of naturally occurring genetic variation, is used to pass wanted traits on to the next generation of organisms. The same process occurred with domesticated animals such as sheep (bred for thicker wool), chickens (considerably larger than their wild ancestors), and cattle (bred for more muscle mass or increased milk yield). Today, the breeding of wheat is a more scientific process; individuals with specific genes are identified and bred to create plants that have improved nutritional content, more intense flavors, and require less fertilizer or pesticide applications. Examples in Agriculture . This is an example of the effect that pressures of modern human populations have on wildlife. The desirable phenotypic traits are passed from parents to offspring via their genes. The animals which are left in the population go on to reproduce, whilst genes controlling for the undesirable traits are removed from the population. 6 Selective breeding has also been practiced in agriculture for thousands of years. a population of insects develops resistance to a pesticide after farmers repeatedly use the same pesticide to kill the insects.
