Selective Breeding & Genetic Engineering

Front

What is selective breeding?

Back

Selective breeding is the process where humans choose individuals with desirable traits to parent the next generation.

Front

What is a genetically modified organism (GMO)?

Back

A GMO is an organism whose DNA has been altered using genetic engineering techniques to exhibit desired traits.

Front

What are some positive reasons for genetically modifying foods?

Back

Positive reasons include producing larger fruits, making pest-resistant vegetables, and creating foods that grow faster.

Front

What are some concerns about genetically modified foods (GMOs)?

Back

Concerns include risks to human health, loss of original genetic lines, and potential harm to ecosystems.

Front

What is the main purpose of selective breeding?

Back

The main purpose of selective breeding is to create animals or plants with desirable traits.

Front

How does selective breeding differ from natural selection?

Back

Selective breeding is controlled by humans who choose traits, while natural selection occurs naturally without human intervention.

Front

What is genetic engineering?

Back

Genetic engineering is the use of technology to cut DNA and insert genes to obtain desired traits in organisms.

Front

What is an example of a trait that can be enhanced through selective breeding?

Back

An example is breeding dogs for specific characteristics like size, temperament, or coat color.

Front

What is the role of DNA in genetic modification?

Back

DNA contains the genetic instructions for an organism, and genetic modification involves altering this DNA to change traits.

Front

What is a potential benefit of GMOs in agriculture?

Back

A potential benefit is increased crop yields, which can help feed a growing population.
