What percentage of CJ bacteria are resistant to FQ?
If allele B made bacteria resistant to antibiotics, which of the following is correct:
What is the total number of blue eye color alleles in these 4 cats? (Homozygous blue eye color)
What is the total number of blue eye color alleles in these 4 cats? (Heterozygous blue and green eye color)
What is the total number of blue eye color alleles in these 2 cats? (Homozygous green eye color)
What is the total number of alleles for eye color in the population of 10 cats?
If someone has a trait that makes them live much longer than other people but they cannot reproduce, what happens to
their fitness?
If the birds only like to eat blue berries, what is the selective pressure the birds are putting on the bushes?
If a bird species that prefers blue berries entered the area, how would it affect the number of bushes that make each color
of berry?
Which type of selection would be caused by this bird species?
Which type of selection would be caused by a bird species that prefers both blue and red berries, but not purple berries?
A bird species likes both red and blue berries, but can digest berry seeds. This means that berries eaten by the bird do not
become bushes, and that the most successful berries are ones that simply fall to the ground. Which type of selection is
caused by this bird species?
A bird species enters the environment, but we do not know which berry color it prefers. Is the bush population more likely
to survive if it has many berry colors, or just one berry color?
You have two populations of beetles, one with 100 individuals and one with 500 individuals. Two trees randomly fall - one
on each population of beetles. Each tree kills 50 beetles in each population and causes genetic drift. Which of the
following is true?
Suppose an entire colony of lemmings is chased by a predator and most of them jump off a cliff and perish. Fortunately, a
few of them don't jump and re-establish their colony (Re-established Colony) and a few of the jumpers land in the water,
survive the fall and establish a second colony on a nearby island (Island Colony). Which of the following characterizes the
type of change causing a reduction in the genetic variation that occurs in these 2 colonies?
Which of the following is an example of gene flow?
An earthquake causes a population of 10 deer with long tails to panic and move to a population of 90 deer with short tails.
Over time, the allele frequency for long tails increases from 10% to 30%.
Match this scenario to its mechanism of evolution.
In a population of goats, the males have horns of different sizes. The male goats compete for females by ramming their
horns into one another. The male goat with larger horns usually wins the fight and gets to reproduce. Over a few
generations, the average horn length of the population gets larger.
Match this scenario to its mechanism of evolution.
In a population of toucans, some have red feathers and others do not. Farmers cleared some of the forest to grow crops
and randomly destroyed many toucan nests. As a result, the frequency of the red feather allele decreased from 65% to
How do you think new proteins affect the fitness of children?
What effect do you think genetic drift would have on the genetic diversity of a population?
Choose which way of evolution caused the FQ antibiotic resistance.
Which of the following conclusions can be made from this experiment?
The CJ bacteria in the chickens at Monita Farms have a high frequency of the allele that causes FQ resistance. If genetic
What do the results tell us about the experiment?
Bacteria that are resistant to more than one antibiotic are called superbugs. Compare the control and antibiotic data from
the three farms and select all the true statements.
This is your final chance to revise your hypothesis. Explain how this new data supports your hypothesis.
What are "superbugs"? Why are they so dangerous?
Explain how this experiment showed that genetic drift was not a cause of the antibiotic resistance
.
Explain how the superbug was created.
