Selective Breeding

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific plants or animals to breed based on desired traits, with the goal of producing offspring that exhibit those traits.

Front

What is another term for selective breeding?

Back

Artificial selection.

Front

What is a major drawback of selective breeding?

Back

One major drawback is that gene variety is lost, which can lead to inbreeding and associated health problems.

Front

What is an example of artificial selection?

Back

Crossing a Labrador and a Poodle to create a Labradoodle.

Front

What health issues can arise from selective breeding?

Back

Selective breeding can lead to health problems in animals, such as genetic disorders and reduced lifespan.

Front

How does selective breeding affect genetic diversity?

Back

Selective breeding reduces genetic diversity by favoring specific traits, which can lead to a limited gene pool.

Front

What is the purpose of selective breeding in agriculture?

Back

The purpose is to enhance desirable traits in crops and livestock, such as yield, disease resistance, and growth rate.

Front

What is hybrid vigor?

Back

Hybrid vigor, or heterosis, refers to the improved or increased function of any biological quality in a hybrid offspring.

Front

What role does genetic variation play in selective breeding?

Back

Genetic variation is crucial for selective breeding as it provides the raw material for selecting desirable traits.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection occurs through environmental pressures, while artificial selection is driven by human choices.
