What else can I help you with?
Which of the following have been produced by selective breeding A horse breeds B cat breeds C dog breeds D all of the above?
Humans have selectively bred all of these: A horse breeds B cat breeds C dog breeds Scientists also cloned-bred Dolly, a Finn Dorset sheep. Dolly was born July 5th, 1996, at the Roslin Institute in Edinburgh, Scotland. Clone-breeding raised many controversies about cloning, while breeding raises few controversies UNLESS the breeding is known to produce defects in offspring.
What are the risks of GMO?
Genetic modification has been a fact for centuries through selective breeding. Though we can manipulate some genes directly today great care is taken. With any new technology there are always unforeseen risks hence the safety precautions. Risks that can be predicted are taken into consideration with the processes. However there is no evidence that there will be mass epidemics, cancers and mutations occurring.
What are arguments fo and against the quagga project?
While the project is progressing well, there are still those who have certain reservations or are outright against the project.It has been argued that there might have been other non-morphological, genetically-coded features (such as habitat adaptations) unique to the Quagga and that therefore, any animal produced by a selective breeding programme would not be a genuine Quagga. Since there is no direct evidence for such characters and since it would be impossible now to demonstrate such characters were they to exist, the argument is spurious. The definition of the Quagga can only rest on its well-described morphological characteristics and, if an animal is obtained that possesses these characters, then by definition, it will be a Quagga.The genetic basis of the Quagga Breeding Project, relies on the demonstration by Higuchi et al (1987) (Mitochondrial DNA of the Extinct Quagga: Relatedness and Extent of Postmortem Change. Journel of Molecular Evolution 25:283-287) that the mitochondrial DNA of the Quagga is identical to that of other Plains Zebras. Therefore the Quagga and other Plains Zebras belong to the same species and consequently the Quagga should be considered merely a different population (or deme), of the Plains Zebra.The only characters that have been used to identify the Quagga are its coat-pattern characters. Therefore if, within a few generations of selective breeding, an animal demonstrating these characters is obtained, it can with full justification be claimed to be a Quagga, since it would possess the same assemblage of coat-pattern genes as the original Quagga. It would not be a "look-alike".Futhermore, since the indigenous grasses in the original habitat of the Quagga are not significantly different from those areas occupied by extant Plains Zebras, and since extant Plains Zebras occupy habitats of similar degree of aridity to those of the Quagga, there is no sound reason for proposing significant adaptive features of the Quagga to its original habitat, and no reason to believe that animals produced in the selective breeding programme would not survive successfully in the region formerly occupied by the Quagga.
What is the purpose of cloning plants?
Tissue culture cloning is the process of taking small parts of specimen plants and creating unlimited numbers of exact genetic copies asexually in a sterile lab setting. This process has been adapted to create genetically altered commercial food and medicinal crops.
How do captive breeding programs affect genetic diversity?
Captive breeding programs can affect genetic diversity in one of two ways. Within the program itself, genetic diversity is reduced, because captive breeding programs only have a limited number of animals to work with. On the other hand, animals from a captive breeding program that are re-introduced to the wild can increase genetic diversity, because they are bringing genes that may have been gone for a long time back into the gene pool.
What are three animals that have been produced by selective breeding?
Horse, Dog, and Cat.
One example of selective breeding?
Most of the domesticated plants and animals you are familiar with have been produced through selective breeding. Dogs, cats, cows, goats, corn, grass, tomatoes, etc .
What process do humans use to influence the traits of a species?
selective breeding; been going on for thousands of years. genetic engineering; been going on for decades.
How has selective breeding been helpful to your current way of life?
Absalutly no way at ALL!
What are some organisms that was been produced by selective breeding?
I'm unaware of any animals which cannot be selectively bred. If offspring are produced through the mating of male and female of the species, you should be able to select for the most desirable traits in both parents. This assumes, of course, that the breeding stock are already in captivity.
Can a quagga be recreated?
Yes. This has almost been done, in fact, say some. A breeding-back programme has commenced, through selective breeding of the southern Plains Zebras.
How has corn changed through the process of selective bred?
Through selective breeding, corn has been altered to have larger kernels, increased pest resistance, and higher crop yields. Additionally, corn varieties have been developed for specific purposes such as animal feed, ethanol production, and human consumption. Overall, selective breeding has allowed for the genetic enhancement of corn to better meet the needs of agriculture and industry.
How has selective breeding been used on humans beings?
it is useful to humans because if they are looking into raising a foal, to grow up to be a great race horse they would want the parents to be healthy and quite fit. Also if they wanted to raise it to be a jumping horse, they would have to mate a healthy and muscular mare with a healthy and muscular stud. Hope that helps with your question? x
What are the features that all the different breeds of dog have been developed from the wolf by selective breeding?
All the breeds have been found to howl at the moon just like the wolf.
What process is a common practice that has been used by farmers for hundreds of year to develop new plant and animal varieties?
It is called selective breeding.
In what ways has selective breeding been useful to humans today and in the past?
Selective breeding has allowed humans to develop crops and livestock with desirable traits such as higher yield, disease resistance, and improved taste. In the past, it helped early humans domesticate animals for agriculture. Today, selective breeding continues to be crucial in ensuring food security and supporting the agricultural economy.
How long humans been using selective breeding?
this process started several years ago many people cant tell when but it was a long time ago anyway
