Objective: SWBAT review chapter 11 material.
Warm-up Questions:
1. Are you going to study tonight for tomorrow’s test?
2. Are you going to complete your journal check tonight?
Chapter 11 Review
Battle Royale-Style
Battle Royale Rules!
• Each person from your team will be up at the board one
time.
• Each person from your team may go up to the board to
assist someone one time. After that they may not be a
helper for the remainder of the game.
• You must show your work with appropriate units for math
problems and Punnett squares.
• You must write in a complete, stand-alone sentence for
explanations (IQIA).
• Lists must be written in order (answers only)
• The point will be awarded for the team with the correct,
complete answer that puts their pen down first.
• Candy for the winning team!!!
Let’s assemble teams!
Team RIGHT:
Andreassen -- Forsman
Team MIDDLE:
Hale – White
Team LEFT:
Roth -- Zinn
You must answer in a complete
sentence!
1. Write one or two sentences that relate the terms
“allele, gene and chromosome.”
Alleles are different forms of genes,
which are located on chromosomes.
You must answer in a complete
sentence!
2. Use Punnett square(s) to show all of the
possible genotypes of offspring from a father
with type B blood and a mother with type O
blood.
Genotype

AA

BO (if dad is BB); BO, OO (if dad is BO)
You must answer in a complete
sentence!
3. Describe two similarities between mitosis and
meiosis. Format: Both mitosis and meiosis
_________.
Many possible answers:
Both are forms of cell division, both go
through PMAT, both have interphase/DNA
replication, both separate sister
chromatids…
You must list the genotypes for the
following parents in order (answers only)!
4. Tall pea plant height (T) is dominant over
short plant height (t). Green seeds (G) are
dominant over yellow (g).
• Heterozygous for both traits
TtGg
• Homozygous tall, heterozygous green
TTGg
• Short, yellow
ttgg
• Short, homozygous green
ttGG
You must answer in a complete
sentence!
5. Describe the difference between
codominance and incomplete dominance.
Codominance is when heterozygous individuals
show both of the other two phenotypes
separately; incomplete dominance shows a
blend of the two phenotypes in heterozygotes.
You must answer in a complete
sentence!
6. Name and describe two different ways that
meiosis increases genetic variability in
gametes.
Crossing over combines maternal and
paternal alleles in individual chromatids;
independent assortment creates random
combinations of maternal/paternal
chromosomes in gametes.
You must answer in complete
sentences!
7. Describe two differences between mitosis and
meiosis. Each difference must include
information about both processes. Format:
Meiosis _________ while mitosis_________.
Many possible answers:
Mitosis = 2 identical diploid daughter cells;
Meiosis = 4 unique haploid gametes
You must list your answers!
8. Rank the following events in the order in
which they occur. Sister chromatids separate,
homologous chromosomes separate, DNA
replicates, 4 daughter cells are formed, crossing
over
DNA replicates, crossing-over, homologous
separate, sister chromatids separate, 4
daughter cells formed
Show your work!
9. Wet earwax (E) is dominant over dry earwax
(e). Construct a Punnett square to show a
cross between two heterozygous people. List
the genotypic and phenotypic ratios.
Genotypic: 1 EE: 2 Ee: 1 ee
Phenotypic: 3 wet: 1 dry
You must list these in order and clearly
distinguish capital from lowercase!
10. Write the possible gametes from the
following parents?
• CcHHSs
• CHS, CHs, cHS, cHs
• Bb
• B, b
• ET, Et
• EETt
Show your work!
11. Two tall green pea plants are crossed. One
plant is heterozygous for height and
homozygous for green pod color, while the other
is heterozygous for both height and for pod
color. Tall (T) is dominant to short (t) and green
pod (G) is dominant to yellow (g). What is the
phenotypic ratio of the offspring in this cross?
• Tall/Green Pod-12
• Short/Green Pod-4
