Front

What causes variations in species?

Back

Mutations are changes in the DNA sequence that can lead to variations in traits among individuals in a species.

Front

What is artificial selection?

Back

Artificial selection, also known as selective breeding, is the process by which humans breed plants and animals for specific traits.

Front

Which species has been significantly influenced by artificial selection?

Back

Front

What is selective breeding?

Back

Selective breeding is another term for artificial selection, where specific traits are chosen to be passed on to the next generation.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations, which can lead to the development of new traits that may be beneficial for survival.

What is the process called when farmers breed only their best livestock?

Back

This process is known as artificial selection.

Front

How does natural selection work?

Back

Natural selection works by favoring individuals with traits that enhance their survival and reproduction in a given environment.

Front

Can artificial selection lead to negative consequences?

Back

Yes, artificial selection can lead to health problems in certain breeds due to a limited gene pool.

Front

What is an example of natural selection?

Back

An example of natural selection is the way peppered moths changed color during the Industrial Revolution to better blend in with their environment.
