7.13CD Reproduction and Selection

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific plants or animals with desirable traits to reproduce, aiming to enhance those traits in future generations.

Front

How can selective breeding increase crop yield?

Back

By choosing to breed corn plants that produce the most kernels, farmers can increase the overall yield of their crops.

Front

What is an adaptation in organisms?

Back

An adaptation is a characteristic that helps an organism survive and reproduce in its environment.

Front

How do some organisms use color change as an adaptation?

Back

Some organisms change color to blend in with their environment, which helps them avoid predators.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is artificial selection?

Back

Artificial selection is the intentional breeding of organisms by humans for specific traits.

Front

Why can artificial selection decrease genetic diversity?

Back

Artificial selection can decrease genetic diversity because it often focuses on a limited number of traits, leading to a population with similar genetic characteristics.

Front

What is the risk of low genetic diversity in a population?

Back

Low genetic diversity can make a population more susceptible to diseases and environmental changes, increasing the risk of extinction.

Front

What role do dense bones play in penguins?

Back

Dense bones help penguins dive more effectively by reducing buoyancy.

Front

What is the difference between adaptation and variation?

Back

Adaptation refers to traits that enhance survival, while variation refers to the differences in traits among individuals in a population.
