6.4 Artificial Selection Quiz

1. The process of choosing parent organisms for desired characteristics is called

• natural selection

• Artificial selection

• random selection

• genetic manipulation

Answer explanation

The process of choosing parent organisms for desired traits is known as artificial selection. Unlike natural selection, which occurs naturally, artificial selection is a human-directed process aimed at enhancing specific characteristics.

What is an example of artificial selection?

• Letting dogs choose their own mate

• Letting plants pollinate on their own

• Crossing a labrador and a poodle to create a labradoodle

Answer explanation

Crossing a labrador and a poodle to create a labradoodle is a clear example of artificial selection, as it involves human intervention to breed specific traits, unlike allowing dogs or plants to mate or pollinate naturally.

Which statement is true comparing natural selection and artificial selection?

• In natural selection, traits benefit humans and in artificial selection, the traits benefit the species

• In natural selection, traits benefit the species and in artificial selection, the traits benefit humans

• In natural and artificial selection, the process takes hundreds of years to occur

• In natural and artificial selection, nature determines what traits will be passed down to offspring.

Answer explanation

The correct statement highlights that in natural selection, traits evolve to benefit the species' survival, while in artificial selection, humans choose traits that serve their own needs, such as agriculture or pet breeding.

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

Answer explanation

Artificial selection, also known as selective breeding, involves humans choosing specific traits in organisms to reproduce, unlike natural selection which occurs without human intervention.

When humans select desirable traits to be passed down to offspring

• natural selection

• artificial selection

Answer explanation

The correct choice is artificial selection, as it refers to humans intentionally selecting desirable traits to be passed down to offspring, unlike natural selection, which occurs without human intervention.

Artificial Selection is

• a new concept

• discovered by Darwin and used ever since

• used for thousands of years

• a 19th century concept

Answer explanation

Artificial selection has been practiced for thousands of years, as humans have selectively bred plants and animals for desired traits long before Darwin's time, making this choice the most accurate.

The change that occurs over long periods of time in the characteristics and diversity of organisms

• natural selection

• artificial selection

• evolution

• acquired characteristics

Answer explanation

The change that occurs over long periods in the characteristics and diversity of organisms is known as evolution. It encompasses the processes that lead to the development of new species and the adaptation of organisms to their environments.

The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.

Answer explanation

The correct choice highlights that in natural selection, environmental factors drive the selection process, while in artificial selection, humans exert influence, making it a key distinction between the two concepts.

Which of these is not a benefit of artificial selection.

• Organism can become stronger

• Breeding can be expensive

• Farmers and breeder will have better business.

• Migration

Answer explanation

Breeding can be expensive is not a benefit of artificial selection; it highlights a potential drawback. The other options describe positive outcomes, such as stronger organisms and better business for farmers.

1. Artificial selection has been a big factor in the evolution of:

• Dogs

• Panda bears

• Snakes

• Jellyfish

Answer explanation

Artificial selection has significantly shaped the evolution of dogs, as humans have selectively bred them for various traits over thousands of years. In contrast, panda bears, snakes, and jellyfish have evolved primarily through natural selection.
