Unit 4
Chapter 11: Continuity of Information Through Inheritance
The goals of this chapter are:
1. to help you to understand that the flow of genetic information from one generation to the next provides
continuity for species
2. to help you to understand that the genotype of an organism limits the range of potential phenotypes
3. to help you to understand that the environment plays an important role in determining phenotypes
4. to help you to understand that there are biological mechanisms that account for the predictability and
variability of genetic patterns
5. to help you to understand that genetics plays a role in determining complex traits such as behavior
6. to help you to learn to make observations, use models to help develop explanations, use probability to make
predictions, collect, analyze and summarize data, using the appropriate sampling size, and interpret data to
develop explanations.
