Which of the following is part of Darwin's theory of evolution?
Geographic isolation will cause speciation
Organisms will create mutations that will all them to survive better
The organisms that can adapt best to their environment will survive
Natural Selection is caused by a natural disaster
Which of the following is an example of natural selection?
Dark mice can hide from predators more easily than light colored mice
Mice compete for food, shelter and mates
A mutation occurs to an allele causing mice to be dark, light and now grey
Mice migrate to the other side of a mountain, causing speciation
Then a tiger and a lion mate, they create a liger. The tiger and lion are not the same species because:
The liger is not able to adapt to its environment
The liger does not live long after it is born
The liger is not a real animal
The liger is not able to reproduce
Which of the following is NOT part of the founder effect
Some members of the group migrate
The new population can have a different allele frequency
Both the original population and new population survive
Can be caused by a natural disaster
The term "fit" means that those members can live longer.
True
False
Having a small gene pool can lead to extinction
True
False
A large highway separates a population of mountain lions resulting in what type of speciation?
sympatric
allopatric
founder
directional
An example of temporal isolation is when one plant blooms in June while another in September
True
False
If there are 50 flowers, 30 red (RR), 15 pink (Rr) and 5 white (r), what the frequency of the recessive allele?
5%
10%
20%
25%
Suppose wing span is a polygenetic trait. Those with both very large and very small wing spans do not survive. This is:
Disruptive selection
Stabilizing selection
Directional selection
Divergent selection
Which of the following IS NOT part of the Bottleneck Effect?
The new population can have a new allele frequency
The new population size decreases
Can be caused by a natural disaster
The populations are geographically separated
The random change to allele freqencies of a population is known as genetic drift.
True
False
Which of the following IS NOT an example of how species interact with each other in order to survive?
Birds and squirrels eat berries from the same blueberry bush
Bacteria have mutations where some can resist certain antibiotics
Viruses mutate to become more easily spread to hosts
Wolves live, hunt and migrate together
Which of the following would PREVENT evolution from occurring?
Large population
Mutatons
Non-random mating
Immigration of new individuals
Sympatric speciation occurs when 2 populations in the same region no longer interbreed.
True
False
Birds of different species develop different mating calls and therefore do not interbreed. This is an example of:
geographic isolation
behavioral isolation
temporal isolation
the bottleneck effect
Since birds and sugargliders can both fly, they evolved from the same ancestor.
True
False
