2/18/14
104th Day of School
Learning goal (7.L.2.2): I will be able to describe how
Punnett Squares are used to predict patterns of
heredity.
Due Today: Late work/Investigative Article
Evening Assignment: Complete missing work!
Complete Gregor Mendel PowerPoint!
Parts of a Research Investigation Article
Please label each section with headings!
Title: Descriptive title about what you did and found (we’ll do this last).
Introduction: Paragraph introducing different types of human traits (inherited vs.
acquired, dominant vs. recessive) and overall purpose of the experiment. The last
sentence should be your hypothesis (what you think you will find). For example, I
hypothesize that dominant traits are more common than recessive traits.
Methods: Paragraph explaining what you did and how you analyzed the data.
Data & Results: In this part you show your data (data table, graphs, pictures, etc)
and WRITE about your data. For example: “Graph 1 shows that 93% of CORE is
right-handed”.
Analysis and Conclusions: One or more paragraphs analyzing your data and
explaining WHY might have gotten those results. Support your analysis with numbers
from your data table or graph. The last paragraph should sum up what you did and
what you found (now you can write your title!)
Research Investigation on Human Traits – Due 2/12/14
In order to compare traits survey data between your class and your family,
it’s helpful to convert our frequency data into percentages (since the total
number of the class is much higher than your family).
 Create a new data table for comparing your data.
 Convert frequency data into percentages and add to new data table.

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 2/21/14
Father of Genetics
Who is Gregor Mendel
and why is his work so
important?
Read pages 80 – 81 C
in the green textbook to
discover who he was.
Mendel's Work
Gregor Mendel
View the following videos
and take notes about
Gregor Mendel. You will
use these notes to create
a PowerPoint about him
and his contributions to
modern genetics.

Your PowerPoint should include the
following slides:
• Slide #1: Who is Gregor Mendel?
(include his biography and a
picture.)
• Slide #2: Pea Plant Experiment
What did he do?
• Slide #3: Pea Plant Experiment
What did he discover?
• Slide #4: Father of Genetics
Why is he called this?

Gregor Mendel PowerPoint due 2/18/14
Answer the following questions on a sheet of paper. You will
use this for practice with Mendel’s monohybrid crosses.
1)The tool used in
showing the possible
outcomes of a
genetic cross is
called a…?
Do Now
2) Mendel’s “factors”
are known as …?
3) The different forms of
a gene are called …?
View the Mendel Pea Plant Video below to help you
understand how alleles are represented on a
Punnett square.

Mendel Monohybrid Cross
Read pages 110-111 C in the yellow textbook.
McDougal Littell textbook p. 111C
Patterns of heredity can
be predicted.
On the sheet of paper with the Do Now complete
the following problem:
1)Create a Punnett square with the following
alleles from two tall pea plants (phenotype): TT,
Tt (genotype).
2)Complete the boxes in the square to show the
combination of alleles from each parent for their
possible offspring. What are the alleles for each
of the 4 possible offspring?
Punnett Square Practice
Hawley Hornets Team
Dr. Batten
Shon B.
Justice N.
Ways you and your family can help fund research to fight childhood cancers
1) Sign up to become a shavee, collect donations, and go BALD on March 1st!
In addition to the satisfaction of helping out someone with cancer, ALL Hawley Hornet shavees
will receive a pass (after March 1st) to “sit with a friend/sunny day pass” for an entire week!
2) Donate money to support Dr. Batten
3) Donate money to support the Hawley Hornets team.
