David Woods, Janece Campbell, Travis Moore; Correlation between biotechnology and its
effects on society; 52 minute class period; Biology I
Motivation:
1. Teacher will show a video on Huntington’s disease involving karyotyping and genetics
2. Bell Ringer Question: Would you marry or have a child with someone that could or you knew
had undesirable traits within their genetic code.
3. Students will answer the following questions to determine a diagnostic
I.
Students will be asked if they think they should be karyotyped before they are allowed to apply
for a marriage certificate.
II.
Construct a punnet square with parents having the code Hh and hh.
III.
Based on your punnet square constructed, what is the percentage chance of the child getting
Huntington’s disease?
IV.
Analyze the question above and identify the odds of the child not inheriting Huntington’s
disease.

Society
Biology Partnership
Students will be able to accurately identify patterns of inheritance in 80% of punnet squares using the
given alleles.
Students will be able to correctly determine the percent of children inheriting a genetic disorder/disease
from 80% of the punnet squares
Presentation and Participation:
Behavior: Lecture
Assign genetic samples to each group of students
Answer Questions on Bell Ringer Class discussion.
Cognitive: Demonstration
Teacher will run gel electrophoresis on sample parent and child dna and compare it against a baseline.
Behavior: lecture (continue)
Lead class discussion in review over:
Dominate/ recessive traits path of inheritance
Punnet squares and Pedigree lines
Review Vocab: Genotype: what is expressed in the alleles/ an organism’s allele pairs? Example Hh
Phenotype: observable characteristic that is expressed as a result of an allele pair. (What you see or
what disorder they inherit.
Pedigree royal Families recessive sex linked Hemophilia “explain”
Applied Genetics chapter in book
Link applied genetics back to the opening bell ringer By asking the question would knowing peoples
genetic make-up before having children with them be a form of selective breeding
Discussion in inbreeding
Are there any pro/ cons of selective breeding? What I any moral implications might there be?
Explain gel-electrophoresis/ check the tank and see how it is going
Cognitive: Summarizing and note taking

Students will be provided a structured note taking sheet to put key terms and ideas in.
Application/Process: Debate
Students will be asked to construct a debate about whether they think they should do DNA testing on
their children while they are in the womb.
Other: Practice
Students will practice the punnet squares for possible percentage outcome of dominant and recessive
traits.
Questions:
(3 higher order—analysis, synthesis, evaluation)
1. Based on the information provided in class, would you still marry/ have children with someone
has undesirable traits in their genetic code.
2. Construct a punnet square with parents having the code Hh and hh.
3. Based on your punnet square constructed, what is the percentage chance of the child getting
Huntington’s disease?
4. Analyze the question above and identify the odds of the child not inheriting Huntington’s
disease.
5. Based on the laboratory experiment run in the class, which is the Dad of the child?
Reflection:
Students will answer questions on selective breeding worksheet and will be graded and returned the
next day.
Answer key for Questions:
1. Answers will vary

2. Child has a 50% change of getting Huntington’s
3. The child has a high probability of getting Huntington’s based on the percentage
4. Parent 2
Safety:
Students have been reviewed safety procedures prior to coming to class the day before. Teacher will
give a quick demonstration during demonstration activity on possible safety problems. Teacher needs
to be aware of all possible electrical safety concerns and keep care. Make sure students are aware that

teacher is running the lab and shouldn’t crowd lab.
Safety reminders will be given when the students first walk in to lab.
 The students could bump into each as they move around the classroom.
 The students could get cut if they break a test tube.
 It is possible that some of the students could be allergic to the agar.
 Teacher should warn students of possible staining of clothing with blue dye
Transformative:
(Accommodations for at least 2 special needs students)
There is 1 ESE student in the class having learning disabilities, he will be provided a longer time to
complete the Selective breeding worksheet. Any students with ESOL will be provided the worksheet in
digital form to translate to their native language. Students with hearing and visual disabilities will be
provided digital forms of the lesson to read to them as well as show bigger print.
Utilize:
Students will possibly need re-teaching on pedigree examples. If it is unclear how DNA traits match with
a parent and child, a reteach example will be given as a motivation tool in the next lesson.
If more than 10% of students fail to correctly complete the punnet square, I will reteach this concept by
providing another sample of a genetic disorder.
