Artificial Selection

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.

Front

How does artificial selection differ from natural selection?

Back

Artificial selection takes a shorter period of time than natural selection because humans actively choose which traits to propagate.

Front

What causes variations in species?

Back

Variations are caused by mutations, which are changes in the DNA sequence.

Front

Are mutations random?

Back

TRUE: Mutations occur randomly and can lead to variations in traits.

Front

What is an example of artificial selection?

Back

Crossing a labrador and a poodle to create a labradoodle is an example of artificial selection.

Front

What is variation in biology?

Back

Variation refers to the differences in traits among individuals of the same species.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations that can be acted upon by natural selection.

Front

Can artificial selection lead to new species?

Back

Yes, artificial selection can lead to the development of new species over time.

Front

What is the significance of selective breeding?

Back

Selective breeding allows humans to enhance desirable traits in plants and animals.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
