Genetic Engineering/Selective Breeding

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

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

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

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

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

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

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

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

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

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