What is an example of artificial selection in plants?

Over the last century, artificial selection has been successfully used to create new hybrids of crops and fruit. For instance, corn can be bred to be larger and thicker in the cobs to increase grain yield from a single plant.

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 is the best example of artificial selection?

So, the correct answer is ‘The Bloodhound dog breed was bred in the middle ages for an excellent sense of smell to be used for hunting’

What is the earliest example of artificial selection?

One of the earliest uses of experimental artificial selection to address evolutionary questions was by Holtorp (1944). He selectively bred Brassica plants that produced an extra cotyledon and reported an increase in frequency of plants with three and even four cotyledons in subsequent generations.

What is an example of artificial selection 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.

Are Bananas an example of artificial selection?

The amazing diversity between different breeds of dogs is a result of generations of selective breeding. Bananas, unsurprisingly, are not the only organisms that have been created by artificial selection.

Which of the following is an artificial selection?

Selective breeding (also called as artificial selection) is the process by which humans breed other animals and plants for particular traits.

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.

What is a good example of natural selection today?

One example of recent natural selection in humans involves the ability to tolerate the sugar, lactose, in milk. In most parts of the world, adults are unable to drink milk because their body switches off the intestinal production of lactase, an enzyme that digests the sugar in the milk, after weaning.

What is an example of natural selection happening today?

Natural selection is still happening in humans

Like all mammals, humans lose the ability to digest milk when they stop breastfeeding. This is because we stop making an enzyme called lactase. In some countries, the population has acquired ‘lactase persistence’, meaning that people make lactase throughout their lives.

What are the two 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.

Are humans an example of natural selection?

In natural selection, genes that confer some sort of survival or reproductive advantage get passed down and persist in a population, while those that lead to lower survival or fewer offspring become less common. There’s no question that natural selection shaped the evolution of humans in our more distant past.

Which of the following animals is a product of artificial selection?

Which of the following animals is a product of artificial selection? Humans have carried out selective breeding on domestic dogs for thousands of years, resulting in the evolution of many varieties of the gray wolf subspecies known as Canis lupus familiaris.

How do humans change animals through artificial selection?

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.

What is a real world example of evolution?

Evolution is present in our daily lives, like when we catch or combat the flu virus. Evolution also plays a role in some of our most pressing global health problems. The human immunodeficiency virus (HIV), for instance, evolves faster than the immune system can keep up with it.
