What is artificial selection in biology?
Selective breeding of organisms to produce domesticated animals with more desirable traits; selective breeding to test for genetic variation and covariation in a population.
What is artificial selection give an example quizlet?
What is artificial selection? Artificial selection is when someone breeds one type of animal, e.g. dog, with another kind of that animal to create a new breed of that animal that contains the characteristics of the two previous breeds of that animal.
What are the 4 examples of artificial selection?
Artificial Selection Examples
- Farming Livestock. Aggressive male stock has been castrated for centuries, while those males with genotypes, phenotypes (dominant traits) of use to humans have been used as breeding stock.
- Dogs. Artificial selection has been used for millennia.
- Wheat.
- Pest Control.
- Fainting Goats.
What is artificial selection Short answer?
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding. Unlike natural selection, artificial selection doesn’t result in evolution or speciation.
Is artificial selection good or bad?
Although it has provided some benefits for humans, the domestication of animals through the use of artificial selection is unethical as it has sometimes been detrimental to the animals’ well-being. This process, although beneficial to society, is unethical as it benefits humans at the cost of these animals’ wellbeing.
Which is the most clear example of artificial selection?
Dog breeding is one of the most common examples of artificial selection. You need only to tune into a dog show on TV to see the power of selective breeding at work. Crossbreeds, for example, are dogs born from parents of two different breeds.
Which is the best example of artificial selection?
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
What is the downside of artificial selection?
Selective breeding can result in better quality products and higher yields in plants and animals that have been bred for specific characteristics. Disadvantages include a reduction in genetic diversity and discomfort for animals that have very exaggerated characteristics.
What are the results of artificial selection?
Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.
