Selective breeding 2

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

Problems with selective breeding include

• Better animals

• Increased meat production

• Animals can have bad health problems

• more diversity

Which is NOT a result of selective breeding?

• Large seedless watermelons that consumer demand

• Bright oranges that are all about the same size

• An insect that matches the color of the environment

• A dog that has been bred to have short hair

Which of the following best represents inbreeding?

• removing DNA from an organism

• changing traits based on environment

• crossing 2 similiar animals

• crossing 2 different animals

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

The purpose of selective breeding is to

• get bigger animals

• get smaller animals

• create animals with desirable traits

• create animals with bad traits
