6. Activity 56: Joe’s Dilemma
February 11, 2011
Getting Started: Do step 1 in the procedure below.
Introduction: Do step 2 in the procedure below.
Challenge: Would you want to find out if you could have a genetic disease? Why?
Why not?
Procedure: See p. D12
7. Activity 55: Plants have genes too!
February 15, 2011
Getting Started: List 5 inherited traits.
Introduction: Read and summarize page D-8
Challenge: What color leaves will you observe on the
offspring of two green parent plants?
Key Words: offspring, gene, heredity, inherited
Procedure:
-Make a predicition of what the plants might look like.
-Set up your plant petri dishes.
Analysis: Q2 p. D-10

9. Activity 56: Karyotypes
February 3, 2015
Getting Started: Where are your chromosomes (DNA) located?
Challenge: What is a karyotype and why do we do them?
Key Words:
Chromosome- “colored bodies” made of DNA and proteins, that
carry the Genes. Humans have 23 pairs. 46 total.
DNA- A twisted ladder molecule that contains the genetic code.
Karyotype- a picture of your 46 chromosomes taken from a single cell.
Procedure:
- Try a karyotype with a partner by hand.
- -Volunteer for the “virtual karyotype”
10. Activity 57: Reproduction
February 4, 2014
Getting Started: Read page D-15. How is
reproduction by two parents different from
reproduction with one parent?
Introduction: Review the three level reading guide.
Challenge: What is the difference between sexual and
asexual reproduction?
Key Words:
Offspring- a new organism
Asexual reproduction- Offspring arising from a
single parent, identical to parent
Clone- an exact copy of a parent
Mutation- a change in the gene of an organism.
Can be good, bad or indifferent.
Sexual reproduction- Offspring arising from two
parents, not identical to parents.

13. Activity 63: February 10, 2015
Getting Started: Why is it that gametes (Sperm/Egg cells) have half
the number of chromosomes or Body Cells?
Introduction: How did the microscope help scientists study genetics?
Challenge: What role do chromosomes play in the
inheritance of genes?
Key Words:
Chromosome – is a single piece of coiled DNA and proteins containing many Genes.
DNA – a molecule found inside of chromosomes that contain Genes (inherited traits).
Genes- Inherited traits (like hair color) that are found on you your chromosomes.
Gametes- Cells used for reproduction (sperm cell and egg cell)
Body Cells- Every cell in you body that isn’t a sperm cell or egg cell.
14. Activity 58: Reproduction
February 11, 2014
Getting Started: Why are children from the
same parents usually not identical?
Introduction: Read p. D-22 . What is a gene?
Gene- section of a chromosome
that determines an inherited
trait.
Allele- the different versions of a
gene. (eg- blue eyes, brown
eyes)
Challenge: How are simple inherited traits
passed from parents to their offspring and
then to the next generation?

18. Activity 59: Gene Combo
March 3, 2011
Getting Started: What did you learn from
yesterday’s activity with Skye and Poppy?
(blue/orange tails)
Introduction: Who was Gregor Mendel?
Challenge:How can tossing coins help you
understand how organisms inherit genes
from their parents?
Procedure: Do coin tossing activity utilizing
sheets 59.1 and 59.2.
Key Words: Allele, Dominant Model,
Probability, Random
No: p. D30 Q 2, 3 and 4
19.
20. • Heterozygous means mixed alleles..... like "Tt" or
"Ss”
• Homozygous means same alleles.... "TT" or "ss”
There are two kinds of Homozygous......
• If you have two large letters you are Homozygous
Dominant "TT" etc.
• If you have two small letter allels you are
Homozygous Recessive "tt" etc.
• Genotype means your genetic make up like TT or Tt.
You are talking about the alleles or genes.
• Phenotype is the actual outcome of the gene.
"Tongue roller" or "Blue Eyes". It is what you see
expressed.
21. Activity 64: March 17, 2011
Getting Started: In what ways do your genes determine who you are and in what ways does
you environment determine who you are?
Introduction: How did the microscope help scientists .
Challenge: How does the environment affect the inherited green color trait of Nicotiana?
Key Words:
Procedure: Read procedure Part a - steps 1 - 5
22. Activity 66: Patterns in Pedigree
March 3 - 4, 2014
Getting Started: Why is using simple organisms, like plants or insects, better for studying
genetics?
Introduction: Read pg. D-56 and answer, “How do you think scientists can study traits in
humans?”
Challenge: How can you use a pedigree to study human traits?
Key Words: Carrier, Co-dominance, Incomplete Dominance, Pedigree
Procedure: Read activity 66 and problem solve with your team to answer STT questions.
29. Activity 42: A closer look.
January 3, 2011
Getting Started: List 10 things made of cells.
Introduction: Let’s read and summarize C-55 together.
Do columns 1 and 2 of KWL chart.

Getting Started: What traits would you add to an
existing organism if you could?
Introduction: Discuss the above question with your
table mates.
Key Words:
GMO- Genetically modified organisms that contains
genes introduced from another species.
GM Foods- Genetically modified food that is
enhanced in some way.
Organic Food- food grown without any additives
