This document provides instructions for classroom activities related to genetics and genetic disorders. It includes directions for students to: 1. Complete warm up questions and place completed work in a safe location. 2. Work on the final day of a genetics lab, completing worksheets on genetic traits and offspring. Any work not finished will be homework. 3. Look up information on genetic disorders and answer questions about three disorders they research. 4. Work with their group to analyze karyotypes and answer questions. The document gives multi-step directions and refers to ongoing classroom assignments on genetics and genetic disorders.

1. Warm Up1.
Finish Warm Up questions from before break (will
go over and collect)
2.
3.
Start todays warm up question (will go over)
place all graded warm ups ion a safe location

2.  Today
is the LAST DAY we will work on this
lab
 Whatever is not completed today is your
responsibility

3. 1.
Your own smiley face has been created
2.
Fill out a “Genetics with a Smile- Offspring” worksheet
3.
Draw out your smiley face WITH COLOR on the back of
your paper
4.
Grab a “Genetics with a Smile-Wrapping It Up!”
worksheet.- use your ORIGINAL smiley face to fill out this
worksheet
5.
*** Create your offspring**** only if time- do not
complete for homework

4. Warm UpComplete todays warm up question
Write down your homework
Get out your “Wrapping It Up” Questions from
yesterday

5. (2) Which smiley face has the most dominant traits?
_____________________ How many? ______ traits
(3) Which smiley face has the most recessive traits?
_____________________ How many? ______ traits
(4) Which traits were a result of incomplete dominance?

6. 5) What is the probability that a smiley face will have a green
face? _____ out of _____ or ____ %
(6) How many smiley faces have a green face, which is a recessive
trait? _____ out of _____ or ____ %
(7) How does your predicted probability for a green face (#5)
compare to the actual results (#6)? Explain.
(8) What is the probability that a smiley face will have an orange
nose? _____ out of _____ or ____ %
(9) How many smiley faces have an orange nose? _____ out of
_____ or ____ %
(10) How does your predicted probability for an orange nose (#8)
compare to the actual results (#9)? Explain

7. (11) Why did you only need to flip the male parent coin to determine the sex
of your smiley face?
(12) How would the smiley faces change if one of the parents were
homozygous dominant for all the traits while the other was heterozygous?
(13) How would the smiley faces change if one of the parents were recessive
for all the traits while the other was heterozygous?
(14) Uncle Smiley, who is heterozygous for a yellow face, married a woman
with a green face. Both of them have always wanted a large family! If they
were to have 12 children, what is the probability that the children would
have yellow faces? How many would have green faces?
Create a Punnett square to help you find your answers.

8. (15) Grandma and Grandpa Smiley are heterozygous for the star eye shape. If
one of their heterozygous children married a girl with blast-type eyes, what
percentage of their grandchildren should have starry eyes?
What percent would have blast-type eyes? Create a Punnett square to help
you find your answers.
(16) Baby Smiley has curly hair, but neither of her parents do! Is this possible?
Create a Punnett square to help you find your answer.
(17) Aunt Smiley has the cutest pointed ears and would love to have children
with pointed ears! What type of ears would her husband need to have in order
for her to get her wish? Give the genotype and phenotype as part of your
answer.

9. A
genetic disorder is a disease that is caused
by an abnormality in an individual's DNA.
 Abnormalities
can be as small as a singlebase mutation in just one gene, or they can
involve the addition or subtraction of entire
chromosomes.
