You dont have to answer it ill just get reported anyway Genetics with a Smile
Part A: Smiley Face Traits
(1) Obtain two coins from your teacher. Mark one coin with a “F” and the other with a “M” to represent each of the parents. The parents are heterozygous for all the Smiley Face traits.

(2) Flip the coins for parent for each trait. If the coin lands with heads up, it represents a dominant allele. A coin that lands tails up indicates a recessive allele. Record the result for each person by circling the correct letter. Use the results and the Smiley Face Traits page to determine the genotype and phenotype for each trait.

On this last part you can either do this on the computer if you know how to draw on the computer if not just draw on your own paper at home and color and make it nice. We will figure out how to submit together as a class. Refer to the link from the worksheet to get the traits and what to draw.

Part C: Create Your Smiley Face!
Use the Smiley Face Traits chart and your results from
Part A to create a sketch of your smiley face in the box.
Once you have completed the sketch, use the drawing
tools in Microsoft Word to create your smiley face!
Two things to remember ...
√ Do not add color on the computer! Print a black and
white copy and then use crayons or colored pencils to
finish it.
√ Don’t forget to give your smiley face a name! You will
also need to include your name as parent and your class
hour.
