If allele B made bacteria resistant to antibiotics, which of the following is correct:

B, The bacteria population is less likely to be killed by antibiotics

What is the total number of blue eye color alleles in these 4 cats? (Homozygous blue eye color)

8

What is the total number of blue eye color alleles in these 4 cats? (Heterozygous blue and green eye color)

4

What is the total number of blue eye color alleles in these 2 cats? (Homozygous green eye color)

0

What is the total number of alleles for eye color in the population of 10 cats?

20

If someone has a trait that makes them live much longer than other people but they cannot reproduce, what happens to

their fitness?

Decreased fitness

If the birds only like to eat blue berries, what is the selective pressure the birds are putting on the bushes?

For more plants to have blue berries

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?

Red: decrease

Blue: increase

Purple: decrease

Which type of selection would be caused by this bird species?

Directional

Which type of selection would be caused by a bird species that prefers both blue and red berries, but not purple berries?

Disruptive

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?

Stabilizing

A bird species enters the environment, but we do not know which berry color it prefers. Is the bush population more

likelyto survive if it has many berry colors, or just one berry color?

Many colors, if all the colors are available it’s guaranteed at least some of the bushes will be given improved fitness by the birds

and likely thrive. If only one is available it’s more likely the birds won’t be able to help them at all and they might all die.

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?

C, The tree falling on the smaller population will have a bigger effect on allele frequency.

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
