• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

Dogs have been mated to produce Laboradors, Beagles, and Poodles. All of these dogs look and behave very differently from one another. This technique of producing organisms with specific qualities is known as

• artificial selection

• selective breeding

• Cloning

• Genetic Engineering

• Cloning

• Gene Therapy

• Natural Selection

• Selective Breeding

The arrows in the diagram below indicate the development of four different varieties of vegetable plants from wild mustard. Each of these varieties was most likely produced as a result of

• changes in light availability

• selective breeding over many generations

• asexual reproduction in the wild for many years

• gene expression based on the environment

Which produces offspring from a single cell of an adult?

• inbreeding.
• mutations.
• hybridization.
• cloning.

Transgenic organisms contain

• genes from other species.
• cells of another organism.
• genes of only one parent.
• one or more human genes.

A molecule containing DNA from two different organisms is called

• a plasmid.
• a polyploid.
• a hybrid organism.
• recombinant DNA.

Advantages of genetically modified crops include(s)

• insect resistance
• drought/freeze resistance
• higher yield
• all of these are reasons for using GMOs
