Worksheet time: 5mins
Some strains of Streptococcus pyogenes, bacteria that causes strep throat, have mutated to be antibiotic resistant. This means antibiotics won’t kill them. Is this a helpful, harmful or neutral mutation for this strep bacteria?
Helpful
Harmful
Neutral
What inference can we make about how Streptococcus pyogenes became resistant to antibiotics over time?
The bacteria's DNA did not allow antibiotics.
The bacteria can cause infections which makes them resistant.
A mutation occurred in the Streptococcus pyogenes DNA making it resistant to antibiotics.
Scientists have genetically engineered Streptococcus pyogenes to make antibiotics.
The upper body of a white-tailed deer is reddish brown during the summer and grayish brown in the winter. This helps the deer stay hidden from predators. Hairs covering the body are short and thin in summer and become long, thick and hollow in the winter. The hollow hairs help the deer stay warm. On days with only a slight breeze, whitetails can pick up the scent 150-200 yards or 600 feet away. Choose a possible mutation a deer could inherit that would be harmful to the deer and its survival:
The fur is bright white in the summer.
Larger ears.
Longer legs.
Bigger ears.
Colorblindness, the ability to tell the difference between red and green, affects mostly males. Where did the mutation occur to cause colorblindness? Select all that apply
The water a mother drank was contaminated with colorblindness.
The mother looked at the sun which damaged the red cones in her eyes so all of her boys now have colorblindness.
Colorblindness occurs when a mother eats a lot of food with green food coloring.
The DNA inside the egg or sperm cell changed.
Look at this pedigree model. Shapes that are colored in mean that individual has the mutation. What can we tell about the way this mutation is inherited?
Only females inherit the mutation.
Only males inherit the mutation.
Both males and females inherit the mutation.
There is not enough information to answer the question.
On line IV, individual #4 and individual #5 have a child. What is the probability their child will be inherit the mutation?
100%
75%
50%
25%
Which of the following is an example of artificial selection? Select all that apply.
Breeding cows to produce more milk.
Inserting DNA in bacteria to produce insulin.
Cross pollinating corn plants to produce larger corn kernels.
Picking out the best looking watermelon at the grocery store.
What problem is solved by genetically engineering tomatoes to ripen more slowly:
Tomatoes often go bad right after they are harvested so by the time they get to grocery stores they have to be thrown away.
Tomatoes are often eaten by the tomato hornworm caterpillar.
Tomatoes often grow too large so they bend the tomato plant and cause it to snap.
Tomatoes often taste bitter.
Which would person would likely want to study artificial selection and genetics in college?
Dog Breeder
Soccer Player
Actor
Business owner
