DISCLAIMERS

Your set of traits makes you uniquely and

wonderfully you! When we start to analyze these as

a group, things can start to look a little weird and

you really start noticing differences. Please

remember to be tactful and respectful as we our

investigating our genetic diversity.

DISCLAIMERS While we have tried to make the traits and information somewhat

realistic, human genetics is an extremely complicated field of research.

Most of the traits indicated are controlled by several genes on many

chromosomes. We tried to pick traits that tend to reflect Mendelian

inheritance as much as possible. However, the traits in this project are

not necessarily the full story and they are probably NOT located on

the chromosomes indicated. Thank you for your indulgence!

DISCLAIMERS We recognize that there might be circumstances where a student

cannot get in touch with one or both parents (deployed, adopted,

divorced, deceased, business trip, etc.). While we appreciate every

effort to find out the information, if you can’t determine this trait for

a celebrity or a parent, please just write: “UNKNOWN” on the

phenotype checklist. We will explain how to determine genotypes

later. If you have questions or concerns, please email your teacher.

There is a STRONG possibility that you will not be able to figure this

one out for your celebrities (I bet they photoshop )… If you can’t

determine this trait for a celebrity or a parent, please write:

“UNKNOWN.”

HINT: if you are having trouble figuring this one out…

1. Put your hands on your lap.

2. Without thinking, pick up your hands and clasp them.

3. Your dominant thumb is on top.

Look at the whites around the iris—the colored portion of the eye. If you can see any white around the top or bottom of your iris, you have "round" eyes. If you cannot see any white above or below the iris, you have "almond" eyes.

POLYGENIC TRAITS

Poly = many, genic = genes Genetics is quite complicated and most traits are actually controlled by more than one gene. In 7th grade, we are not required to talk about concepts such as incomplete dominance, codominance, and polygenic traits, but they are pretty interesting. All traits that involve color and pigment are polygenic and quite complicated. However, we thought you would want to estimate the skin, hair, and eye color of your child. So, you are welcome to use this information, but you will not be tested on it. If you were unable to use the chart in class, use the science 7 website to see the color pictures to determine your polygenic genotype. There are also links in your project for additional information about polygenics!
