One allele is not completely
dominant over the other allele;
appears as a blending of the trait
Coiled DNA found in nucleus;
structure containing DNA and
proteins
Process of cells reduction division of
chromosomes; produces gametes
Reproductive cell; eggs and sperm
Specific characteristics
Traits determined by genes located
on the X chromosome
In the first meiotic division
chromosomes exchange segments
of their DNA
The likelihood, or chance,
something will happen
A change in the DNA
Containing a single (half) set of
chromosomes; chromosome
number of gametes
Containing a double (full) set of
chromosomes; 23 pairs in humans
Genes for different traits can sort
independently during the formation
of the gametes
Form of a gene that does not show
its trait when the dominant gene is
present
Diagram showing possible gene
combination among offspring of the
parent generation
The genes an organism has for the
traits they possess
The physical description of the
genes an organism possesses; how
an organisms look
17. What conclusion can be drawn from the
genetic information above?
F The white parent carried a dominant
allele.
G All the F1 rabbits carried a recessive
allele. _
H All the white rabbits are heterozygous.
J All the black rabbits in the F2
generation are homozygous.
18. A genetic pedigree showing that only
males are affected by a certain disorder is
evidence of what type of inheritance?
A Dominant
B Sex-linked _
C Recessive
D Passive
19. The jimsonweed Datura stramonium,
normally has 12 chromosomes in the
body cells. How many chromosomes
will an egg cell of the weed have?
A 6 chromosomes _
B 12 chromosomes
C 18 chromosomes
D 24 chromosomes
20. In corn plants, green (G) is dominant
to albino (g). According to the Punnett
square, what is the chance of this
heterozygous cross producing albino
corn plants?
A One in four _
B Two in four
C Three in four
D Four in four
21. The Human Genome Project was begun
in 1988 by scientists from 13 nations as
a worldwide effort to understand the
sequencing of all of the DNA in the
human body. What is one potential
scientific benefit of this research?
F It will help to explain human cultural
differences.
G It will create communication between
research centers.
H It will help find the genes responsible
for many diseases. _
J It helps to classify man most accurately
in the animal kingdom.
22. In rabbits, short fur (F) is dominant to
long fur (f). According to the Punnett
square, what is the chance of two
heterozygous short-haired rabbits
having offspring with short fur?
A One in four
B Two in four
C Three in four _
D Four in four
23. In cows, long hair is dominant to short
hair. In a cow that is heterozygous for
long hair, what percentage of the cells
undergoing meiosis will carry the
dominant allele?
F 25%
G 50% _
H 75%
J 100%
24. People who have been exposed to
excessive radiation often experience
mutations. If these mutations only
occur in somatic (body) cells, these
people may —
F pass on these mutations to their
offspring
G experience an increased risk of cancer _
H develop entirely new DNA sequences in
all cells
J experience difficulties replicating RNA
