Must meet in nature & have gene flow
b)
Must be able to reproduce & share a gene pool
c)

d)
Offspring must be fertile
2.
Fruit flies are beginning to live & mate on different types of fruit on the floor of the Amazon. Bigger fruit flies prefer rotting mangos, while smaller fruit flies prefer rotting bananas. What type of reproductive barrier is this?
a)
habitat isolation
b)
temporal isolation
c)
gametic isolation
d)
mechanical isolation
3.
A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?
a)
behavioral isolation
b)
temporal isolation
c)
gametic isolation
d)
geographic isolation
4.
The pollen (sperm) of a flowering plant cannot fertilize the egg cell of a nearby flowering plant of its kind. What type of reproductive barrier is this?
a)
behavioral isolation
b)
temporal isolation
c)
gametic isolation
d)
geographic isolation
5.
When reproductive barriers separate a population of a species in nature, the species no longer share a...
a)
taxa
b)
gene pool
c)
phylogenetic tree
d)
species
6.
The genitalia of the male damselfly varies in shape. Certain males can only hold onto & mate with females whose genitalia fit. What type of reproductive barrier is this?
a)
behavioral isolation
b)
temporal isolation
c)
gametic isolation
d)
mechanical isolation
7.
When a zebra & horse mate, they create a zorse. Zorses are most often sterile. What type of reproductive barrier is this?
a)
behavioral isolation
b)
hybrid sterility
c)
gametic isolation
d)
mechanical isolation
8.
Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?
a)
behavioral isolation
b)
hybrid sterility
c)
temporal isolation
d)
mechanical isolation
9.
The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?
a)
behavioral isolation
b)
hybrid sterility
c)
temporal isolation
d)
mechanical isolation
10.
The term for the formation of new and distinct species over the course of evolution is...
a)
speciation
b)
biological species concept
c)
reproductive barrier
d)
natural selection
11.
Fish with a yellow stripe on their bellies are beginning to prefer to only mate with other fish with yellow belly stripes. When a fish without a stripe mates with a fish with a yellow stripe, they still have fertile offspring. Both types of fish live in the same body of water. What type of speciation is this?
a)
Early separation
b)
Mid separation
c)
Late separation
d)
This species will stay the same forever!
12.
Frogs that live along the west coast are showing preference for mating calls. Frogs toward the north are small & have bumpy skin & make a high pitch croak. Frogs toward the south are larger, with smoother skin & have low croak. They sometimes overlap in nature and when they do, create fertile offspring. What type of speciation is this?
a)
Early separation
b)
Mid separation
c)
Late separation
d)
This species will stay the same forever!
13.
Lions and tigers do not overlap in nature. When they are held in captivity together, they can breed and create sterile ligers and sterile tigons. What type of speciation is this?
a)
Early separation
b)
Mid separation
c)
Late separation
d)
This species will stay the same forever!
14.
What is a species?
a)
A group of organisms that can mate with each other and produce fertile offspring.
b)
A group of organisms that can mate and produce offspring even if those offspring are infertile.
c)
A group of organisms that genetically are very different from each other.
d)
Indivual organisms that live in the same environment.
15.
What evidence does speciation provide for the theory of evolution by natural selection?
a)
Speciation can show us that new species don't choose to adapt, but have changed due to diverging from an original species due to reproductive barriers.
b)
Speciation can show us that new biological species can come from divergence (separating) due to reproductive barriers.
c)
Speciation can show us that environmental changes & genetic variation play a role in the process of a new species diverging from an original species due to reproductive barriers.
d)
All of the above fit!
