When a farmer breeds only his or her best livestock the process involved is?

chapter 15

Question Answer
When farmers select animals or plants to use for breeding, they look for natural variations that are present in a species
when a farmer breeds only his or her best livestock, the process involved is artificial selection

What is the process in which humans breed organisms for certain traits?

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Which statement is part of Darwin’s theory of evolution by natural selection?

Darwin’s Theory of Evolution by Natural Selection More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

Which of the following phrases best describes the results of natural selection?

Evolution Test

Question Answer
Which of the following phrases best describes the results of natural selection? Changes in the inherited characteristics of a population over time.
Which statement is in agreement with Darwin’s theory of evolution? More offspring are produced than can possibly survive

Which of the following best describes the difference between artificial and natural selection?

The following statement best describes the difference between artificial and natural selection: Natural selection acts without the input of humans: artificial selection requires human input. only via natural selection, genetic drift, migration, or mutation.

Which of the following are examples of artificial selection?

The Brassicas are great examples of artificial selection. Cabbage, broccoli, cauliflower, Brussels sprouts, collards, and kale are all members of the same species, Brassica oleracea. Gardeners have cultivated flowers sh as roses and orchids, carefully manipulating heredity to produce the “perfect” hybrid.

Which explains how new dog breeds come into existence?

Which explains how new dog breeds come into existence? Humans developed dog mating programs that selected for certain traits. Farmers identified the plants that produced the largest tomatoes and selected only these plants to reproduce.

What are four main principles to the theory of natural selection?

There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.

What are the three main ideas of natural selection?

Natural selection is an inevitable outcome of three principles: most characteristics are inherited, more offspring are produced than are able to survive, and offspring with more favorable characteristics will survive and have more offspring than those individuals with less favorable traits.

What is a major advantage of natural selection?

Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

How do you explain natural selection to a child?

Natural selection is the process where organisms that are best suited to their environment survive and pass on their genetic traits in increasing number to successive generations. At the same time, organisms that are less adapted fail to survive or multiply at a lower rate, and tend to be eliminated from the ecosystem.

What is the definition of survival of the fittest?

Survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing.

What does Darwinian mean?

1 : of or relating to Charles Darwin, his theories especially of evolution, or his followers. 2 : of, relating to, or being a competitive environment or situation in which only the fittest persons or organizations prosper. Other Words from Darwinian Example Sentences Learn More about Darwinian.

Why is survival of the fittest important?

Darwin’s theory of evolution by natural selection is one of the most important concepts and organizing principles of modern biology. And because of its clarity, the phrase “survival of the fittest” is still widely used to explain natural selection to people interested in understanding the evolution of life on Earth.

Who said survival of the fittest?

Herbert Spencer

Does survival of the fittest still exist?

While the phrase “survival of the fittest” is often used to mean “natural selection”, it is avoided by modern biologists, because the phrase can be misleading.

Why doesn’t survival of the fittest mean survival of the strongest?

Explain your answer. Survival of the fittest” means survival of the “strongest”, “toughest”, “fastest”, “smartest” or “most attractive”. “Survival of the fittest” isn’t about being the toughest, fastest, or most attractive. It’s about surviving to pass the genes that encode traits and behaviors on to offspring.

What is survival of the fittest quizlet?

Survival of the Fittest. process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection.

Does evolution always favor traits that make sense?

Natural selection doesn’t favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

Which of the following best describes genetic drift?

Explanation: Random fluctuations in the gene frequencies within a population Eliminate is the one which best describes genetic drift.
