Which of the following best describes a GMO (genetically modified organism)?
German Shepherd puppies bred from two German Shepherd parents.
Watermelon plants that were intentionally cross pollinated with pollen from a different variety of watermelon.
Salmon (fish) that have been altered with a growth hormone gene from another type of fish.
A sheep that was created as a result of cloning.
A dog breeder selects a male bulldog to breed with their female bulldog to reproduce more bulldog puppies. This is an example of
line breeding.
hybridization.
Humans with genetic diseases can have a gene inserted into their body using a virus that has been genetically modified with a beneficial gene. This is best described as
gene therapy.
cloning.
selective breeding.
genetic engineering.
A farmer collects seeds taken from a plant that produces the largest tomatoes of the season. He will then plant those seeds next year to produce more of the same large tomatoes. This is an example of
line breeding.
hybridization.
Someone has a wild cat breed (reproduce) with a house cat in order to have a cat offspring that looks wild but is more gentle. This is an example of
line breeding.
hybridization.
Which best describes the use of technologies to correct mistakes in DNA that cause diseases or disorders?
gene therapy
genetic engineering
selective breeding
cloning
Choosing which organisms to use as parents to reproduce offspring is_____.
selective breeding
genetic engineering
gene therapy
cloning
What is an example of "line breeding" by farmers?
Mating 2 small chickens to create more large chickens
Mating 2 large chickens to create more large chickens
Mating a large chicken and a small chicken to get medium chickens
Using a machine to change the DNA of a chick
Scientists want to genetically engineer corn plants to be immune to corn diseases. What might happen as a result?
Corn plants would be less likely to reproduce.
An increase in corn plants dying from diseases.
This would cause ears of corn to be smaller.
This would allow an increased production of corn.
Zoos have bred white tigers to produce white tiger offspring for generations. White tigers in zoos are now more likely to be born with birth defects because they are closely inbred. This is a __________ effect of selective breeding.
harmful
beneficial
Why would scientists want to clone cows?
To produce cows with genetic variation.
To produce adult cows instead of having to raise baby cows.
To produce cows with the same strong, healthy genes as a parent cow.
To replace chickens and goats, which are harder to clone.
Directly making changes in the DNA of an organism in a lab setting is called
cloning
hybridization
genetic engineering
line breeding
What process is shown in the picture?
genetic engineering
cloning
selective breeding
gene therapy
Putting the gene for bioluminescence (allowing them to give off light!) into a fish is an example of
genetic engineering
selective breeding
gene therapy
cloning
Scientist might use genetic engineer to produce crops that
are insect resistant.
can handle drought or freezing temperatures.
produce more fruit/vegetables.
all of these are reasons for creating GMOs
Rice plants modified to produce more Vitamin A by inserting new genes into its DNA sequence.
genetic engineering
cloning
selective breeding
gene therapy
Cotton plants designed to resist pests and pesticides by altering the plants' DNA.
genetic engineering
cloning
selective breeding
gene therapy
Diabetes is a disease that causes high blood sugar. Genetically modified bacteria can be used to deliver working copies of a gene into the body to help correct the issue. This is an example is best described as
gene therapy.
genetic engineering.
cloning.
selective breeding.
