Artificial selection is the identification by humans of desirable traits in plants and animals , and the steps taken to enhance and perpetuate those traits in future generations.
What is artificial selection Kids definition?
Artificial selection is the intentional breeding of plants or animals . It means the same thing as selective breeding and is an ancient method of genetic engineering. Selective breeding is a technique used when breeding domesticated animals, such as dogs, pigeons or cattle.
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 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.
What is artificial selection an example of?
An example of artificial selection – Dog breeding
Nowadays, these domesticated animals are what we call dogs! Domestication is the act of separating a small group of organisms (wolves, in this case) from the main population, and select for their desired traits through breeding.
What is the best example of artificial selection?
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. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.
Is artificial selection good or bad?
Artificial selection in animals raised for consumption is unethical and harmful to both the animals being selected as well as the producers who raise them. An unfamiliar environment is needed to domesticate animals to suit human needs, causing both psychological and physical stress.
How do you explain natural selection?
Natural selection is the process through which populations of living organisms adapt and change . Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
What’s the difference between artificial and natural selection?
The difference between the two is that natural selection happens naturally , but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
How do humans breed?
Humans mate through a process called sexual intercourse . Human reproduction depends on the fertilization of a woman’s ova (egg) by a man’s sperm.
What are the types of artificial selection?
In The Variation of Animals and Plants Under Domestication, Darwin (1868) considered two types of artificial selection in addition to natural selection 1 : methodical selection and unconscious selection . As he explained (Darwin 1868, p.
What are the risks of artificial selection?
- It may lead to a lack of variety in plant or animal species. ...
- Genetic mutations are still going to occur. ...
- The process of selective breeding becomes about humans only. ...
- There is no guarantee that the desired traits will pass to the offspring. ...
- It can create genetic bottlenecks.
What is the cause of artificial selection?
Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock . This process is called artificial selection because people (instead of nature) select which organisms get to reproduce. ... This is evolution through artificial selection.

What is a real life example of natural selection?
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds .
What are 3 types of artificial selections?
- 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. ...
