Winter Holiday Genetics Worksheets

Since many teachers found my Creature Genotype and Phenotype Differentiated Worksheets helpful for their classrooms, I decided to make another version with holiday characters like Santa, Frosty, and the Grinch. In these holiday genetics worksheets students find the percent chance of certain genotypes and phenotypes appearing in the babies of these famous characters. Two versions of the same worksheets are in this document so teachers can easily differentiate for the students in their classroom. 

Two sample questions are shown below with their differences highlighted.  You'll notice that just a few changes of the wording can create more of a challenge for students because they have to use their vocabulary knowledge to determine the parents' genotypes before creating a Punnett square and solving for the baby.

Sample Question from Worksheet A:

Spice the gingerbread woman and Stan the gingerbread man want to know what kind of buttons their little one will have. Frosting buttons are dominant and candy buttons are recessive. Spice is FF and has frosting buttons. Stan also has frosting buttons but his genotype is Ff. What are the possible genotypes and phenotypes of their baby?

Sample Question from Worksheet B:

Spice the gingerbread woman and Stan the gingerbread man want to know what kind of buttons their little one will have. Frosting buttons are dominant and candy buttons are recessive. Spice is homozygous for frosting buttons and Stan is heterozygous. What are the possible genotypes and phenotypes of their baby?

I had a lot of fun being creative and making these winter holiday Punnett square worksheets and I think students will like them as well. Check them out now while Teachers Pay Teachers is having a site wide sale. Remember to use the Promo Code TPTCYBER to get the full discount of 28%.
