I made this game for a 7th grade science review.

3. Punnett Square – 100
A four-sided tool used for
predicting traits
Punnett Square

4. Punnett Square- 200
What‟s the first step in solving
the following problem?
If you cross a homozygous dominant
purple pea plant with a heterozygous
pea plant, what’s the probability of the
offspring being purple?
underline the important
information

5. Punnett Square 300
After underlining, what‟s the next
step in solving the following
problem?
If you cross a homozygous dominant
purple pea plant with a heterozygous
pea plant, what’s the probability of the
offspring being purple?
Figure out what is dominant and
what is recessive

6. Punnett Square 400
After figuring out what‟s dominant
and recessive, what‟s the next
step for solving the problem of:
If you cross a homozygous dominant
purple pea plant with a heterozygous
pea plant, what’s the probability of the
offspring being purple?
Labeling for mom and dad or plant 1 or plant 2, etc.

7. Punnett Square- 500
What‟s the last step before
making the cross to complete
a Punnett Square?
Place alleles (genotypes) on
the top and side of the square

8. Punnett Square, Too!- 100
Cross a homozygous brown-
eyed man with a homozygous
brown-eyed woman. Brown
is dominant. Use the letter
„B‟.
B B
B BB BB

9. Punnett Square, Too! - 200
Cross a heterozygous brown-
eyed man with a blue-eyed
woman. Brown is dominant.
Use the letter „B‟.

Cross a blue-eyed woman
with a blue-eyed man. Use
the letter „B‟.

plant with a hybrid pea
plant. Purple is dominant.
Use the letter „P‟

pea plant with a white pea
plant. Purple is dominant.
Use the letter „P‟

13. _______gous – 100
Two alike alleles are known
as
homozygous

14. _______gous - 200
A genotype with different
alleles is known as
Heterozygous

15. ______gous - 300
HH, for example
Homozygous dominant

16. ______gous - 400
hh, for example
homozygous recessive

17. _____gous - 500
When two chromosomes on
a chromatid are alike, it‟s
called…..
homologous

18. Do the Math - 100
The likelihood that an event
will occur
Probability

the offspring having a
heterozygous genotype?

offspring having a
phenotype of brown eyes?

23. Hodgepodge - 100
Who is the “Father of
Genetics”?
Gregor Mendel

24. Hodgepodge - 200
What is a pea pod?
The outermost casing which
holds peas, the delicious
round vegetables, in place.

25. Hodgepodge - 300
When Gregor Mendel used
only purebred pea plants in
his experiments, he was
using the principal of:
Selective Breeding

26. Hodgepodge - 400
Yellow is recessive. For pea
pods, which color would
show if you had two
recessive alleles?
yellow

27. Hodgepodge - 500
What‟s the probability of
having a yellow pea pod
when each parent has a
homozygous dominant
genotype? Green is
dominant
0%
