Selective Breeding, Genetic Engineering

It is very common for yellow labs to have bad hips. This is because owners want purebred yellow labs who are good hunting dogs.  This is an example of 

• Natural Selection
• Selective breeding
• Mitosis
• Fossil Record

All of the following statements are reasons for selective breeding except:

• To produce offspring with desirable characteristics
• Farmers increase their profit by improving crops
• To improve the quality of food products
• To increase migration patterns

The purpose of selective breeding is to 

• Get bigger animals
• get smaller animals
• create animals with desirable traits
• create animals with bad traits

What is one reason why people are against genetic engineering?

• There is a high risk of failure
• It has a 100% success rate
• People do not like dogs

Scientists genetically engineer corn to be immune to corn diseases. This is BENEFICIAL because

• This causes corn to be less likely to reproduce
• This causes corn to be less likely to survive
• This causes corn to be smaller
• This allows increased production of corn
