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
Which is another term for selective breeding?
artificial 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?
genetic manipulation
natural selection
random chance
artificial selection
Within a species, a number of characteristics remain the same from one generation to the next. Explain the reason for this.
characteristics in a species are physical
characteristics in a species are genetic
characteristics in a species are environmental
characteristics in a species occur by chance
The passing of traits from parent to offspring is called?
reproduction
diversity
heredity
chromosome
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
inbreeding
hybridization
cloning
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
Crossing a red sweet apple with a large disease resistant apple is an example of ________________.
inbreeding
cloning
natural selection
hybridization
Sean is studying the advantages of selective breeding in plants. He made the following list of possible advantages:
1) can produce corn that attracts grasshoppers
2) can develop grass that can grow with less water
3) can develop wheat that can grow in different types of soil
4) can produce oranges that are not affected by freezing temperatures
Which items on the list provide logical arguments in favor of selective breeding?
1,2,3
2,3,4
2,4
3,4
Problems with selective breeding include
better animals
more meat
animals can have bad health problems
more diversity
Which of these is a common example of selective breeding?
a lion being born in the wild
tomato plants that produce fewer tomatoes
crops that catch diseases
cows that produce lots of meat
Which is an example of selective breeding in plants?
Reduced yield
Disease resistance in crops
Increased pests
Where is most genetic variation found?
between lions and tigers
within one species

What occurs when a sperm meets an egg?
fertilization
menstruation
variation
What is one of the processes involved in selective breeding?
allowing organisms to reproduce without interference
choosing individuals with desirable characteristics to be parents of the next generation
Which statement explains how a population’s genetic variability and diversity can be affected by selective breeding?
Genetic variability and diversity decrease because only select individuals are bred.
Genetic variability and diversity increase because only select individuals are bred.
Genetic variability increases and diversity decreases because only select individuals are bred.
Genetic variability decreases and diversity increases because only select individuals are bred.
