Genetics with a Smile Task Card
Part A: Smiley Face Traits: Record your data in DATA TABLE A
1. Obtain two coins. The penny represents the female (Penny’s) genotype and the nickel represents the male
(Nick’s) genotype.
2. Holding both coins in your hand, flip them to determine which allele each parent will pass to Baby Smiley.
Heads = Dominant Trait Tails = Recessive Trait
A. On the table below, circle the allele Penny passed on to Baby Smiley in the column labeled “FEMALE” and
the allele Nick passed to Baby Smiley under the column labeled “MALE”.
B. Based on the outcome of the coin toss, write the genotype of Baby Smiley in the “GENOTYPE” column.
C. Based on Baby Smiley’s genotype, use the provided Smiley Face Traits to determine Baby Smiley’s
phenotype for each trait. Record the data in the “PHENOTYPE” column.
Part B: Is Baby Smiley a boy or a girl?
To determine the sex of Baby Smiley, flip the coin for the male parent. Add the gender to the Data Table B.
Heads = Y (male) Tails = X (female)
Part C: Create Baby Smiley!
Obtain a Face Shape based on
your data. Using Data tables A
and B, create an accurate
representation of your Baby
Smiley based on the phenotype
you created. Once you have
created Baby Smiley, give him/
her a name and write the name
on the line.
Sex:
To determine the sex, flip a coin for the male parent. Heads = Y and tails = X

Assignment #:_________Block:________ Genetics with a Smile Mr. & Mrs. Smiley have decided that it is time to expand their family. The Smiley’s, whose first names are Nick
& Penny, are both heterozygous for each of the twelve traits that their offspring will inherit. During this activity
your job is to:
1. Determine the genotype for Baby Smiley by flipping a coin; based on the genotype, determine
the phenotype of Baby smiley
2. Determine Baby Smiley’s Sex
3. Create Baby Smiley & name him/her
4. Complete the evaluation questions

16. Star eyes are dominant over blast eyes. Grandma and Grandpa Smiley are heterozygous for the star eye shape. If one of their heterozygous children married a smiley with blast shaped eyes, what percentage of their grandchildren should have star eyes? Complete the Punnett square to help. ____________________________
