Artificial selection is the basis of both domestication, and modern plant and animal breeding. Humans have carried out artificial selection over more than two thousand year and cultivated wild cabbage as a food plant, and generated different vegetables from it.
What are some examples of artificial selection in plants?
Artificial selection on wild mustard For example, cauliflower, broccoli, cabbage, kale, and kohlrabi bear little superficial resemblance to their wild mustard relatives. And yet, through many generations of artificial selection, these five distinct crops were intentionally evolved from a wild, weedy ancestor.
Why is the wild cabbage a good example of evolution?
The wild cabbage is a good example to prove that Entirety different looking organism can evolve from the same organism by the process of evolution . The only difference is that we are using artificial selection of evolution instead of natural selection .
What fruits and vegetables have been improved through artificial selection?
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. Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs.
What is an example of selective breeding in biology?

What is artificial selection explain it with an example of wild cabbage class 10?
Some have selected for swollen parts, and come up with kohlrabi. Some have simply looked for slightly larger leaves and come up with a leafy vegetable called kale. So, cabbage, cauliflower, broccoli, kohlrabi and kale are descended from the same ancestor, wild cabbage by artificial selection.
What is artificial selection explain with an example?
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.
Why cabbage is an artificial selection?
Folks have been munching on B. oleracea for millennia. It was mentioned by Greek and Latin scholars before the dawn of Christian Rome. Early farmers domesticated the wild cabbage by selecting plants with certain traits and breeding them, a process called artificial selection.
Is cabbage artificially selected?
Explanation: Cabbage, cauliflower and broccoli are artificially selected plants. Four varieties of vegetables that have been produced from 'wild cabbage' under the process of artificial selection are cabbage, kale, kohlrabi, and broccoli.

What are the evolution of wild cabbage?
Answer. The evolution of wild cabbage was through artificial selection, meaning that human beings selected the characters they wanted and bred for these characters only. For example when they wanted a lot of leaves, they created cabbage. When they want arrested flower growth, they created broccoli.

What is the difference between natural selection and artificial selection explain with examples?
Natural selection is a nature-made selection, and artificial selection is a man-made selection. The main difference between natural and artificial selection is that natural selection produces a great biological diversity whereas artificial selection produces varieties of organisms such as improved crops and livestock.
What is an example of natural selection?
A classic example of natural selection at work is the origin of giraffes' long necks. The ancestors of modern giraffes were animals similar to deer or antelope, with necks of ordinary length.
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 is artificial selection?
artificial selection. Noun. breeding to produce desired characteristics in animal or plant offspring. biologist. Noun. scientist who studies living organisms. breeding. Noun. practice of selectively pairing breeding pairs of animals together to achieve desired traits in animal offspring.
What fruits and vegetables have been improved or even created through artificial selection?
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.
What is the principle of natural selection?
Sometimes summed up by the phrase “survival of the fittest,” natural selection is based on the following principles: In nature, organisms produce more offspring than are able to survive and reproduce. Offspring with traits that make them more likely to survive, mature, and reproduce in the environment they inhabit pass on their traits to ...
How does natural selection affect the environment?
Organisms therefore gradually become better-suited for their environment. If the environment changes, natural selection will then push organisms to evolve in a different direction to adapt to their new circumstances.
Why is artificial selection important?
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. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding. Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs.

But Darwin was also inspired greatly by the evolution that he saw in the traits of pigeons, not due to natural selection but rather artificial selection. Breeding pigeons was a popular hobby in England in Darwin’s time.

However, there are some disadvantages of artificial selection, especially in the case of inbreeding. Through inbreeding, two closely related organisms reproduce to yield a purebred with desired traits.
What is selective breeding?
Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Breeders select two parents that have beneficial phenotypic traits to reproduce, ...
What is the difference between kale and broccoli?
Broccoli, for example, was developed from wild cabbage plants that had suppressed flower development while kale was derived from Brassica oleracea with larger leaves. 5 . Corn, or maize, is an unusual product of selective breeding.
