Unit Overview:
The study of some genetic disorders will be used to anchor the learning. Students will assume a fictional identity during this unit. Each student will be given a profile card containing the genotypes of their blood type, PTC tasting ability, and a genetic disease disorder. Students will learn about meiosis and heredity, and then research several genetic disorders. Students will couple with another student to determine the genetic make-up of an offspring. Biotechnology processes will be used. Students will conduct a DNA extraction and a microarray will be performed as a way of checking the genotypes of the offspring.
Enduring Understanding:
Genetic information can be used to predict traits passed from one generation to the next.
Indicators:
3.7.C.1 Explain the ways that genetic information is passed from parent to offspring in different organisms.
AGOPPE Research Process
A-Ask Questions
How is genetic information used to predict the traits of offspring?
What is the role of meiosis in distributing genes from parent to offspring?
How are genetic disorders passed down through families compared to the transmission of communicable disease?
Describe the following disorders: Huntington’s Dsease, Cystic Fibrosis, Sickle Cell Anemia and Achondroplasia. What are the causes (mode of inheritance), symptoms, and treatment options for each disease?
What systems of the body are affected by these diseases?

O-Organize Information
***Use your DISEASE RESEARCH CAPTURE SHEETS to organize your findings.
Use Noodle Tools for your Works Cited Page, You must use at least 3 credible sources.
P-Present Information
You will present your findings to the class in a 5 minute presentation. Presentation (if in power point, presentation printed as hand outs) Include a picture if possible
P-Present Information
Student couples will group with another couple, who will be playing the role of genetic counselors. Genetic counselors will consult with the couple, gather information about their genotypes and phenotypes and then create a Genetic Counselor’s report. The students then switch roles, with the counselors becoming the parents and vice versa.
