Acquired Trait
Definition/characteristics: A trait or
characteristic that is developed or
learned through life. Traits you aren’t
born with. Traits GENERALLY not
controlled by DNA.
Examples:
Walking, speaking English,
dyed hair, pierced ears,
Glasses, skin cancer?

Genetics Vocabulary Flashcards due 2/28/14
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)
Genetics Projects
Sickle Cell Anemia
Description: Sickle Cell Anemia is a recessive genetic disorder
caused by a mutation that deforms the hemoglobin proteins in
red blood cells leading to a sickle shape.
Cause: Sickle cell anemia is caused by a single mutation in the
hemoglobin gene on chromosome 11 resulting in a change in the
hemoglobin protein.
Inheritance: Sickle cell anemia is a recessive disorder. Patients
who carry only one allele for the sickle cell mutation (Ss) are
carriers of the sickle cell trait. Only people who inherit two
mutated alleles have sickle cell anemia (ss).
Incidence: SCD affects 90,000 to 100,000 Americans. SCD
occurs among about 1 out of every 500 Black or AfricanAmerican births. SCD occurs among about 1 out of every 36,000
Hispanic-American births. SCT occurs among about 1 in 12
Blacks or African Americans. (Source: CDC)
Treatment: There is no cure for sickle cell anemia however you
can treat the symptoms. Pain medication, Hydroxyurea (reduces
painful crisis), blood transfusions, antibiotics (to prevent
infections especially in children).
Sickle Cell Anemia
McDougall p. C146-147
Sickle cell anemia is a recessive genetic disorder
affecting red blood cells. What are the chances of a
child being born with sickle cell anemia if both the
father is a carrier of the sickle cell trait (Ss), but the
mother is not (SS)?
