5. List and describe the three stages of labor.
1. What is the difference between dominate and recessive genes?
2. What is the difference between heterozygous and homozygous expression of genes?
3. Using Activity 2 found in your Laboratory Manual, create a Punnett square and complete the exercise associated with incomplete dominance.
4. View Figure 45.1 from your Laboratory Manual and identify the structures that are described by the following statements. Briefly discuss the concept of sex-linked inheritance in the threaded Discussion Area below. (Completion of Activity 3 in your Laboratory Manual should help with this.)
