Genetic Engineering/Selective Breeding

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 an example of selective breeding?

Back

A farmer breeding pineapple plants from the sweetest pineapples to get even sweeter plants is an example of selective breeding.

Front

What are genetically modified organisms (GMOs)?

Back

GMOs are organisms whose genetic material has been altered using genetic engineering techniques.

Front

What are some concerns about GMOs?

Back

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

What genotype(s) express the dominant trait of brown hair?

Back

Both BB and Bb genotypes express the dominant trait of brown hair.

Front

What is genetic engineering?

Back

Genetic engineering is the manipulation of an organism's DNA to achieve desired traits, such as inserting a gene for bioluminescence into fish.

Front

What is natural selection?

Back

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

Front

What is artificial selection?

Back

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

Front

What is a dominant trait?

Back

A dominant trait is a genetic trait that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A recessive trait is a genetic trait that is only expressed in the phenotype when two copies of the allele are present.
