Choose the phrase that best
represents macroevolutionary change.
New forms of animals
replacing older ones
In a certain population,
the frequency of a dominant allele is represented by p = 0.7, and the frequency
of the recessive allele is represented by 0.3. What is the frequency of the
heterozygous genotype?
Whales are descendents of: a relative of a
The evidence for evolution
includes which of the following?
All of the choices are
All of the following are
correct about Intelligent Design except:
it is scientifically testable
The Hardy-Weinberg
equilibrium is based on a number of assumptions. Which of the following is NOT
one of those?
Mating occurs nonrandomly,
and mates exert preferences.
A population of frogs
developing a slight difference in their mating calls is an example of
microevolutionary change
Over time, the same bones
in different vertebrates were put to different uses. This falls under the
category of:
homologous structures
The hypothesis that
suggests evolution occurs slowly and changes in organisms are nearly
imperceptible is:
Most types of organisms
evolve at about the same rate.
The fossil record indicates
that whales evolved from:
hoofed mammals
If two species of plants
bloom during different seasons in the same habitat, this is known as:
temporal isolation
________________ results
from microevolutionary changes that increase the likelihood of survival and
The molecular evidence of
how the cytochrome c gene changes with time suggests that this gene
at a constant rate
Two populations of flowers
are separated by a mountain range and would not be capable of interbreeding.
This is an example of:
geographical isolation
Bees may pick up pollen of
one species on a certain place on their bodies; if this area does not come into
contact with the receptive structures of the flowers of another plant species,
the pollen is not transferred. This is an example of:
mechanical isolation
A structure remaining in an
animal but with no use at all is called:
The hypothesis that
suggests evolution occurs in spurts, with a great deal of evolutionary activity
followed by periods of slower evolution is:
punctuated equilibrium
Sickle-cell anemia in
humans is an example of:
stabilizing or balancing
All of the following are
examples of vestigial structures except:
human gall bladder
When selection operates to
eliminate intermediate phenotypes, it is referred to as:
disruptive selection
The notion that organisms
that are more distantly related should have time to accumulate more biochemical
differences than those more closely related can best be illustrated using:
a molecular clock
In pools below waterfalls, where
predation is _____, male guppies are _____, whereas in pools above waterfalls
where predation is ______, male guppies are ______.
high, drab colored, low,
more colorful
Choose the phrase that best
represents microevolutionary change.
Changes in allele frequency
in a population
In small populations, gene
frequencies can change drastically by chance alone. This phenomenon is called:
genetic drift
