Biology Unit 9 Human Genetics and Genetic Technology Layered Assignments
Alan Dewey
Wabasso High School
OBJECTIVES
1. Be able to analyze a pedigree
2. Understand how some human traits differ from regular Mendelian genetics, including incomplete dominance and codominance, blood types, and sex-linked traits.
3. Understand how a karyotype can be used to predict genetic abnormalities in fetuses.
4. Describe how some diseases can sometimes be predicted by genetic testing and how this affects parental and community decisions.
5. Recognize that artificial selection has led to offspring through successive generations that can be very different in appearance and behavior from their distant ancestors.
6. Describe the social, economic and ecological risks and benefits of biotechnology in agriculture and medicine. For example: Selective breeding, genetic engineering, and antibiotic development and use.

Day 14- Layer A work day/All assignments due
LAYER B- APPLICATION OF KNOWLEDGE (10 points)
____
*1. Choose one human trait we looked at in lab
(tongue rolling, ear lobes, widow’s peak, etc). Collect
information from your family (10-20 people) concerning the trait (male,
female, who does or does not have the trait). Construct a
pedigree for the trait including genotypes, phenotypes, and a
key. This project will need to be done all on your
own time and will be due at the very end of the unit.
LAYER A- CRITICAL THINKING & ANALYSIS OF REAL WORLD ISSUES (15 points)
Using
2 resources cited below, either write a 1 page paper or create a 6
slide powerpoint presentation exploring one of the questions
below. When answering questions the first paragraph should be
an introduction, the second paragraph should give information (pro and
con), and the last paragraph or slide should include your conclusion
and opinion on the question posed. Make sure you relate your
question to material discussed in class.
____ 1. Is biotechnology (genetic engineering) good or bad for agriculture? What has been its effect on a specific plant or animal?
____ 2. Is human cloning good or bad? Why is it so controversial?
____
3. Is stem cell research good or
bad? Why is it so controversial?
