Module 2: Genetics, Prenatal Development, and Birth

In this module, we will discuss concepts related to conception and heredity. We explore how fetal development is additive and varied, guided by the genetic material supplied by both biological parents. We will also look at how development typically proceeds and some causes of genetic abnormalities. Before going into these topics, however, it is important to emphasize the interplay between heredity and the environment. This chapter helps us understand why parental health is important during conception and pregnancy, how social support and reduced stress benefit a developing fetus, and why we are the way we are. As you consider some of your features (height, weight, personality, being diabetic, etc.), ask yourself whether these features result from heredity or environmental factors. Chances are, you can see how both heredity and environmental factors (such as lifestyle, diet, and so on) have contributed to these features. 

1. Examine our basic genetic endowment and explain how human development can go awry (CLO #2)
2. Explain how the environment and genetics work together to determine human characteristics (CLO #2)
3. Determine which human characteristics are significantly affected by heredity (CLO #2)
4. Determine which human characteristics are significantly affected by the environment (CLO #2)
5. Recognize and express the prenatal stages of development (CLO #2)
6. Name the threats to the fetal environment and articulate what can be done about them (CLO #2) 

To achieve these objectives: 

1. Read the Module 2 Introduction
   
2. Complete the following assignments: 

• Read Chapter 2 (LO 1-6)
• Facts About Conception and Pregnancy (LO 5)
• Buying Eggs or Finding a Sperm Donor or Surrogate on the Internet (LO 6)
• Childbirth Related Policies (LO 4 & LO 6)
