Genetic Technology

Selective breeding is...

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

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

An example of selective breeding is

• a dog breeder mating 2 dogs to make more dogs

• a farmer grows bees to pollinate the plants on his farm

• a person pollinates 2 white rose plants to only create white roses

One problem with selective breeding is

• creating a new species

• gene variety is lost

• extinction of a species

Which is another term for selective breeding?

• Artificial selection
• Natural Selection
• Intelligent selection

Evidence shows that the wolf is the ancestor to all of the breeds of dogs shown below. How did this variation arise in a relatively short period of time?

• A.  Genetic manipulation
• Natural selection
• Random chance
• Selective breeding

How do scientists cut DNA into smaller strands?

• restriction enzymes
• scissors
• ligase
• agarose

The process of making changes in the DNA code of a living organism is called

• selective breeding 
• genetic engineering
• inbreeding
• hybridization

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

In order for natural selection to occur, what must exist in a species?

• Stability

• Low mutation rate

• Variation

The process of man choosing organisms with the most desirable traits and mating them is known as

• Cloning

• Natural selection

• Selective breeding
