1.
What do you call all of the genes in a population?
a)
Gene pool
b)
Relative Frequency
c)
Genetic Drift
d)
Allele pool
2.
Genetic drift is likely to be seen in a population
a)
That has a low mutation rate
b)
In which natural selection is occurring
c)
That is very small
d)
For which environmental conditions are changing
3.
If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?
a)
The population will evolve, but much more slowly than normal
b)
The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.
c)
The composition of the population's gene pool will change slowly in a predictable manner.
d)
Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.
e)
The population probably has an equal frequency of A and a alleles.
4.
What type of selection is depicted in the picture?
a)
stabilizing
b)
directional
c)
disruptive
d)
the answer is not here
5.
What type of selection?
a)
Directional
b)
Stabilizing
c)
Disruptive
6.
Robins typically lay fours eggs. If more then four eggs are produced then the baby chicks are malnourished while smaller egg numbers result in no viable (able to live) baby chicks. This is an example of
a)
stabalizing
b)
disruptive
c)
direction
d)
none of the above
7.
If finches with large beaks and finches with small beaks increase in a population while finches with average sized beaks decreases, which pattern of natural selection has occurred?
a)
Directional selection
b)
Disruptive selection
c)
Stabilizing selection
8.
Which is not one of the 5 H-W assumptions?
a)
No mutation
b)
No natural selection
c)
Random mating
d)
Extremely small populations
9.
A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.
a)
gene pool
b)
founder effect
c)
bottleneck
d)
mutation
10.
Ten years ago, in a small population of ducks, two sizes of eyes were observed, large and small. Three ducks have large eyes and 7 have small. 2 of the large-eyed ducks are randomly hit by cars and killed. Today, no large-eyed ducks are present in the population.
a)
gene flow
b)
bottleneck
c)
mutation
d)
founders
Reset
