1.Which of the following is NOT one of the principles of natural
selection?
a.all living things vary
b.more organisms are born than can obtain food and survive
c.organisms reproduce exponentially
d.organisms are perfectly adapted to their current environments
2.Features that are influenced by genetic material and the
environment are called:
a.genotypes
b.phenotypes
c.variants
d.a and b
3.Biological evolution is composed of:
a.the accumulation of small changes in a short time period
b.large scale changes in a lineage over many generations
c.small changes noticeable to a casual observer
d.a and b
4.Selection for characters that do not deviate in either direction from
an optimal range of values in a population is called:
a.stabilizing selection
b.directional selection
c.disruptive selection
d.genetic selection
e.adaptation
5.When a protein that is specified by a gene or sequence of DNA is
produced,it is called:
a.transcription
b.translation
c.protein synthesis
d.replication6.The production of sex cells is:
a.mitosis
b.meiosis
c.cell division
d.replication
e.recombination
7.The only source of new alleles,or alternate forms of genes,is:
a.gene flow
b.genetic drift
c.mutation
d.selection
e.all of the above
8.Refer to the chart below.What is the phenotype of individual
number 6 in this chart?
a.It is impossible to tell whether they have A or B blood because you
do not know which allele is dominant.
b.they have type O blood.
c.they have type AB blood.
d.they have type A blood.
e.they have type B blood.
10.A change in allele frequencies from one generation to the next is:
a.evolution
b.genetic drift
c.gene flow
d.mutation
e.cline
