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

• natural selection

• Artificial selection

• random selection

• genetic manipulation

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

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.

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

When humans select desirable traits to be passed down to offspring

• natural selection

• artificial selection

Artificial Selection is

• a new concept

• discovered by Darwin and used ever since

• used for thousands of years

• a 19th century concept

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

• natural selection

• artificial selection

• evolution

• acquired characteristics

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.

These cause variations.

• mutations

• adaptations

• a desire to change

• breeding

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
