Subject: Biology
Grade Level: 10th Grade
Unit Title: Unit 2- Inheritance and Molecular Genetics
Timeframe Needed for Completion:
3 weeks (on a 90 min per day schedule)
Grading Period: 1st Nine Weeks
Big Idea/Theme: Genetics
Understandings:
This unit is focused on patterns of inheritance and genomics. Students will learn how genes interact, how traits are expressed, how
scientists study this inheritance, and current applications of this knowledge. Specifically, students will gain an understanding of:
 Mendelian genetics
 Complex inheritance patterns including incomplete dominance, codominance, multiple alleles, polygenic traits, and sexlinked traits.
 How to interpret pedigrees and karyotypes
 Uses of genomics including the Human Genome Project and applications of biotechnology.
 inheritance patterns and their control in blood typing
 Understand various human genetic disorders focusing on new treatments, the inheritance, the diagnosis, their application
to biology
 Understand how the environment, and/or the interaction of alleles, influences the expression of genetic traits.
 Understand how traits are determined via the structure and function of DNA.
 The process of gel electrophoresis and DNA Fingerprinting
 Transgenic Organisms and bacterial transformation
Curriculum Goals/Objectives (to be assessed at the end of the

1. Do you look like your parents? Why or why not?
2. How can we make predictions about what our children and
our grandchildren will look like?

Bio.3.3 Understand the application of DNA technology.
Bio.3.3.1 Interpret how DNA is used for comparison and identification
of organisms.
Bio.3.3.2 Summarize how transgenic organisms are engineered to
benefit society.
Bio.3.3.3 Evaluate some of the ethical issues surrounding the use of
