GENETICS:
1. _____ What statement is most correct:
A. all humans genes are located outside the nucleus of the cell.
B. A human only has one gene for each trait
C. Most organisms have two genes for each trait, one on each of the homologous
chromosomes in the cell’s nucleus
D. There are organisms that do not have any genes.
2. _____What statement about DNA and inheritance is correct?
A. a child’s DNA will be unrelated to the mother’s or father’s DNA.
B. A child’s DNA will show similarities to both the mother’s and father’s DNA.
C. A female child’s DNA will exactly match the mother’s DNA.
D. A male child’s DNA will exactly match the father’s DNA.
3. _____ If a normal human’s body cells contains 46 chromosomes, the sex cells contain:
A. 12 ½ chromosomes
B. 23 chromosomes
C. 46 chromosomes
D. 92 chromosomes
4. _____ If dimples in humans are due to a dominant gene, when two parents are crossed,
each whom are heterozygous (Dd) for the trait, what percent of offspring would be
expected to have dimples:
D
d
A.
B.
C.
D.
25%
50%
75%
100%
D
d
5. _____When genes are carried on the X (sex) chromosome, they are termed X-linked or
sex-linked. Which of the following statements would be true concerning recessive traits
that are inherited on the X chromosome.
(Female sex chromosomes are XX and Males are XY)
A. boys would always inherit the recessive trait if their mother was
homozygous dominant for the trait
B. boys can not inherit this trait from their mothers at all.
C. boys will inherit this trait only from their fathers.
D. boys will inherit this trait from their mothers if the mom is homozygous
recessive.
6. _____ True or False:
If a mother and father are each homozygous dominant for a trait, they can have a child
who is recessive for that trait.
7. _____ In the ABO blood group, A and B are codominant and O is recessive.
If one parent has genotype AB and the other parent has genotype OO.
TRUE or FALSE: They can have children who have AB blood and children who have
O blood.
A
B
EVOLUTION
8. ____ True or False: Fossils and embryological development are both used to support
the concept that organisms change over time.
9. _____ Sexual reproduction is better for evolution because:
A. all of the offspring will have the same genes
B. Asexual reproduction causes different genes in each generation
C. Sexual reproduction allows for a mixing of genes through the fertilization of egg
with sperm which were both formed through the process of meiosis.
D. The statement is false, asexual reproduction is better for evolution
10. _____ The process described by Charles Darwin by which evolution occurs is called:
A. Natural Selection
B. Mutation
C. Acquired traits
D. Lamarckian evolution
11. _____ What statement is most true:
A. fossils may be dated using radioisotopes such as Carbon 14
B. The deeper a fossil is found, the younger (less old) it is.
C. There is no such thing as fossils
D. All fossils are bones.
12. _____ Populations of organisms can be affected by which of the following factors:
A. immigration
B. birth rate
C. death rate
D. food availability
E. all of the above
13. _____ If a population of yeast is grown in a test tube and this population is measured
by the amount of carbon dioxide gas given off, what would you expect to happen as the
amount of food is increased in the test tube?
A. the yeast population would die
B. the yeast population would increase and therefore more carbon dioxide is given
off
C. the yeast population will decrease
D. the yeast population will increase and the amount of carbon dioxide given off
would decrease.
14. _____ Based on the theory of evolution by natural selection, which statement best
explains why modern giraffes have long necks:
A. giraffes were selectively bred by humans to encourage the development of long
necks
B. more giraffes with long necks lived to produce more offspring than did giraffes
with short necks
C. a disease that did not affect giraffes with long necks wiped out all giraffes with
short necks
D. years ago, giraffes reaching up to eat leaves on tall trees gradually stretched their
necks
BIODIVERSITY
_____15. Carolus Linnaeus developed a system of naming and classifying organisms.
This system uses Kingdom, Phylum, Class, Order, Family, Genus, and Species to

the:
A. kingdom and phylum
B. phylum and class
C. class and order
D. family and genus
E. genus and species
_________16. The six kingdoms of life are: Eubacteria, Archaebacteria, Protista, Fungi,
Plantae, and Animalia. Which of these kingdoms have the ability to photosynthesize and
are multicellular?

species that can interbreed. Which of these groups could be considered a population?
A. all of the lions in the world
B. the white tailed deer of Connecticut

other as other kingdoms differ from each other
