What is an example of artificial selection in animals?

What is an example of artificial selection in animals?

A common example of artificial selection in animals is dog breeding. As with racehorses, particular traits are desirable in different breeds of dogs that compete in dog shows. The judges look at coat coloring and patterns, behavior, and even teeth.

What are 3 examples of selective breeding?

Selective breeding

• cows that produce lots of milk.
• chickens that produce large eggs.
• wheat plants that produce lots of grain.

Which examples of artificial selection are caused by human activity?

Growing human organs from pig stem cells because of increased research on stem cell therapy. A decrease in rams’ horn size because of hunters’ preference for long-horned rams. Cows producing milk with more protein because of genetic engineering. Chickens producing more meat because of selctive breeding.

What is one of the most common examples of artificial selection?

Animal Breeding: Livestock, Dogs, and Others Dogs provide among the most startling examples of the effects of artificial selection. Various dog breeds have been created by humans over the past 10,000 or more years starting from the common ancestor of all dogs, the gray wolf.

What is artificial selection give an example?

Artificial selection is when a human determines two organisms to mate and tries to predict the results with regard to one trait. For instance, let’s say you want a fast race horse. You go out and choose a male and female horse that are both very fast and have won races.

What are some examples of artificial and natural selection?

Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits. Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.

Which of the following are examples 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.

What is a real life example of natural selection?

Examples of Natural Selection Examples in Animals During rainy times, more small seeds were produced and the finches with smaller beaks fared better. Since the environment supports both types of beaks, both remain in the population. Peacock females pick their mate according to the male’s tail.

Which is an example of artificial selection quizlet?

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 was the first organism to be artificially selected?

Ancient Genetic Modification The dog is thought to be the first organism our ancestors artificially selected. Around 32,000 years ago, while our ancestors were still hunters and gatherers, wild wolves in East Asia joined groups of humans as scavengers.

Which is an example of artificial selection in evolution?

Artificial selection, also called ” selective breeding ”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection. An example of artificial selection – Dog breeding

How is artificial selection used in food production?

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.

How long has artificial selection been in use?

Artificial selection has been used for millennia. It is estimated that it has taken approximately 14,000 years of selective breeding to produce the huge number of ‘pure-bred’ dogs today, although the phrase pure-bred is incorrect, as only the original breed – the gray wolf – is, in essence, pure.

How does artificial selection affect quality of life?

However, artificial selection can also be used to damaging effect. Often, it is the quality of life of the artificially-selected species that is affected, such as respiratory infections and hypoxia in short-nosed dogs, and fainting in goats.
