Mike and his three brothers all have brown hair. Mike's
father has brown hair, too. Mike's mother, however, is the
only family member that has red hair color. What
conclusion can you draw about the gene for hair color?
a. The gene for red hair is dominant over the gene
for brown hair.
b. The gene for brown hair is dominant over the
gene for red hair.
c. Neither brown nor red are dominant since they
both occur in the same family.
d. Red and brown genes are co-dominant.
18. Single-celled organisms can reproduce and create
cells exactly like themselves without combining
genes from two different parent cells. When they do
this, they use a type of
a.
asexual reproduction.
b.
gamete formation.
c.
natural selection.
d.
sexual reproduction.
30.Which animal embryo grows inside
a shell?
a.whale
b. rabbit
c.
mouse
d. bird
This unicellular organism is
reproducing asexually by what
method?
If a cell lacked ribosomes, it would
be unable to
A) Manufacture carbohydrates for the cell to
use
B) Make food through the process of
photosynthesis
C) Manufacture proteins using genetic
material from the nucleus
D) Transport materials throughout the cell.
3.
When a cell of a plant stem divides, each
new cell has
a.
b.
c.
d.
half the number of chromosomes as
the parent cell.
the same number of chromosomes as
the parent cell.
twice the number of chromosomes as
the parent cell.
four times the number of chromosomes
as the parent cell
8.
What is true of the offspring of organisms
that reproduce sexually?
a.
b.
c.
d.
They are genetically identical to one of
the parents.
Genetically, they are completely
different from their parents.
They have some genetic traits of both
parents, but are not exactly like either.
They always have twice as many
chromosomes as their parents, since
they have two parents.
Mendel proposed that traits observed in pea plants
resulted from a combination of "factors" inherited
from each parent. His description of these "factors"
can be considered the first scientific definition of the
role of —
a.
ribosomes
b.
meiosis
c.
genes
d.
cell nuclei
21. Brown eyes are dominant to blue eyes. Both of
Donna's parents have brown eyes, but Donna has blue
eyes. What is the BEST explanation for why Donna
has blue eyes?
a.
b.
c.
d.
All of Donna's grandparents must have had
blue eyes.
Both of Donna's parents carry a gene for
blue eyes.
Donna's mother probably carries the gene
for blue eyes.
Donna's father probably carries the gene for
blue eyes.
