the required information. Check answers when
finished.
5) When done sit quietly and …

questions that you have about the project you have
chosen.
Quiz on Traits, Mendel, and Punnett Squares
A characteristic that an
organism can pass on to
its offspring through its
genes or can be
developed or learned.
Question #1
A trait which is
developed or learned
during your life.
Question #2
A trait which you are
born with.

example of a(an)…
Question #4
1. Draw a Punnett square.
2. Then label where the male
and female genotypes are
written
Question #5
In pea plants, green pod color (G) is dominant over
yellow pod color (g). Create a Punnett square of a
cross between a hybrid male plant with green pods
(Gg) and a female plant with yellow pods (gg).
Question #6
In pea plants, yellow seed color (Y) is dominant
over green seed peas (y). Create a Punnett square
of a cross between a male and female plant both
heterozygous for yellow seed color (Yy).
Question #7
What is the probability that the offspring of this
cross will be Yy?

cross will have green seeds?

Question #9
In pea plants, round peas (R) are dominant over
wrinkled peas (r). Create a Punnett square of a
cross between a female male plant homozygous for
round peas (RR) and a male plant homozygous for
wrinkled peas (rr).
Question #10
What is the probability that the offspring of this
cross will be Rr?

Question #11
In humans, brown eyes (B) are dominant over blue
(b). A brown-eyed man marries a blue-eyed woman
and they have three children, two of whom are
brown-eyed and one of whom is blue-eyed. Use
the correct Punnett square to show the genotypes
of the parents and the children.
Question #12
The different forms of a
gene.
Question #13
The Father of Genetics
Question #14
Having two identical alleles
for a trait.
Question #15
Give an example of a
homozygous dominant
genotype.
Question #16
An organism’s physical
appearance, or visible
traits. “What you see”
Question #17
An allele whose trait shows
up in the organism with
only one copy.
Question #18
Having two different alleles
for a trait.
Question #19
Give an example of a
heterozygous genotype.
Question #20
An allele whose trait shows
up in the organism only
when two identical copies
of the allele are present.
Question #21
An organism’s genetic
makeup. “The genes it
has”
Question #22
The passing of genes from
parents to offspring.
Question #23
A pet store owner has three guinea pigs:
1. Purebred Black
2. Hybrid Black
3. purebred brown
If the store owner wants to get more brown guinea
pigs, which two should he breed?
What is the probability of getting a brown guinea
pig from this cross?
Question #24
Gregor Mendel was from…
Question #25

Choose the genetic project you would like
to complete.
Write down any questions that you might
have if you do not understand how to do
the project you have chosen.
Evening Assignment
Choose ONE of the following projects to do as a summative MAJOR assessment for the
Genetics Unit. Do detailed, quality work to get full credit.
Selective Breeding vs. Genetic
Modification
Corn is one of the most
manipulated crops. Create a
Presentation or Poster
comparing traditional selective
breeding vs. genetic
modification (GMO). Explain
the two methods and then show
some specific corn
varieties/cultivars that were
created with each method and
how.
Genes associated with
inherited traits
We learned about several
common inherited human traits.
Pick at least 10 traits to research
and which genes control these
traits. Include pictures of the
traits phenotypes as part of your
presentation. You may complete
as a Word document or
presentation.
Inheritance of Eye Color
Create a Powerpoint
presentation about the genetics
of eye color. Include information
about the different types of eye
color, any genes that are
associated with eye color, and
how eye color is inherited. In
your final slide, explain how
YOU inherited your eye color.
Myths of Human Genetics
Dr. John McDonald from the
University of Delaware has
written that many of the
inherited traits students learn in
genetics class AREN’T really
inherited in a simple dominant
vs. recessive pattern that is
taught. Create a Powerpoint to
review his arguments and
compare it to what MOST
genetics students learn.
Meiosis Game
Create a game to help students
learn the steps of meiosis.
Students must answer questions
about chromosomes, genes,
DNA, and meiosis to advance
through the stages of meiosis I
and meiosis II. You win when
you reach the final gamete stage.
Plant Genetics
Grow two different species of
plants and create a digital
comparison of their phenotype
similarities and differences
(appearance, size, growth rate,
etc). Then research the genetics
of the two species summarizing
what you find. Include the
number of chromosomes and
genome size
Expanded Traits Survey
Create YOUR OWN survey of
ten inherited traits. You may use
5 of the ones we did but must
include 5 new ones. Sample at
least 50 people. Write up your
finds as a Research Investigation
Article – but with more detailed
and thorough sections than we
did as a class.
Genetic Disorders
Create a Presentation about a
specific genetic disorder. You
must include the following
information about that disorder:
description, signs/symptoms,
how it’s inherited or acquired,
genes affected (including the
mutation if known), incidence,
and treatment.
GMOs in the News
Farmers and scientists use
GMOs to create better crops.
Write a news article picking a
specific GMO and discuss the
process, the benefits, and risks
of using that GMO
History of Genetics
Create a timeline about the
history of genetic knowledge
starting with ancient times (ex.
Biblical times) through the
present. You must have at least
15 descriptions along the
timeline.
Selective Breeding in Dogs
Dog Breeders use selective
breeding to improve dog breed.
Create a brochure to explain the
selective breeding process and
use specific examples to show
how breeders have gotten new
dog breeds.
Pedigree Analysis
Create a pedigree of at least
three generations using a single
inherited trait. You must use a
REAL family either your own or
one you research. Include a
Punnett square from each
generation to show how that trait
was inherited (3 total)
