Genetics & Identity Portfolio Project

As we learn about human inheritance, you will be creating a ‘portfolio’ of personal examples and reflections on genetics.  This work is expected to be entirely your own- you are UNIQUE!

Possible traits: achoo syndrome, ear wax types, lactose intolerance, traits from the “Inventory of Traits” lab.

Page 4: Make your own punnett square: Co-dominance 

• Possible traits: Blood type

Page 5: Make your own punnett square: Incomplete dominance

• Possible traits: Curly hair/wavy/straight.  Another example of an intermediate expression may be the pitch of human male voices.  The lowest and highest pitches apparently are found in men who are homozygous for this trait (AA and aa), while the intermediate range baritones are heterozygous (Aa).

• Possible traits: Hair color

• Height (3+genes)
• Eye color (15+ genes)
• Skin color (378+)

• societal implications
• scientific evidence

I am from the__________________________________________ (description of your home)

_______________________________________________ (a detail about your home-a smell, taste, or feel)

I am from the_________________________________ (plant, flower, natural item)

The_______________________________________ (plant or tree near your home)

Whose long gone limbs I remember

As if they were my own.

I'm from______________________and___________________ (a family tradition and family trait)

From___________________and____________________________ (family members)

I'm from_______________________and________________________ (family habits)

Simple Punnett Square

Create a Punnett square using a ‘simple’ complete dominance trait.  Examples confirmed with research: lactase persistence (D) vs. lactase nonpersistence (R); ear wax: wet (D), dry (R); Achoo syndrome (D), no syndrome (R); astigmatism (D), no astigmatism (R) online test for asigmatism:  http://www.essilor.com/en/EyeHealth/LensesForYourVision/TestyourEyes/Pages/ EyetestforAstigmatism.aspx

http://udel.edu/~mcdonald/mythintro.html see this website for information on how nearly every trait we teach as complete dominance is not a true example. The one exception is ear wax.

Reflection: How does this punnett square show ‘you’? Does this connect to your experiences? Why or why not?  Is this trait something that affects your identity?

Co-Dominant Punnett Square

Create a Punnett square using a co-dominant human trait. Codominant traits include: Blood type,  Blood cell shape/Sickle Cell Anemia,

Incomplete Dominance Punnett Square

Create a Punnett square using an incomplete dominant human trait. Incomplete dominant traits include: curly/wavy/straight hair, pitch of voice.

Pitch of voice info: “An example of intermediate expression is the pitch of a human male voice. Homozygous men have the lowest and highest voice for this trait (AA and aa).” (https://en.wikibooks.org/wiki/Human_Physiology/Genetics_and_inheritance#Unifactorial_Inheritance)

Polygenic Inheritance

Choose one polygenic trait to explore: height, eye color, skin color, hair color.

Link to eye color calculator website (takes multiple genes into account):

TRAIT:______________________  

Possible phenotypes: ________________________________________________

My Phenotype: __________________________

Most polygenic traits can be thought of as a ‘continuum’.  There will be many phenotypes within a population.  For some traits, we can think of a ‘range’ as a way of expressing the number of people and the expression of multiple genes.  For the trait you’ve chosen, label the axes on the graph below.

While some of these traits may be controlled by way more than 3 genes, we’ll use a Punnett Square with 3 genes for simplicity.  Where do you think your phenotype falls in this square? Why?
