Unfortunately they have not updated the applet yet, so you may not be able to run the actual simulation, but read the Heritability Introduction section to learn what a heritability value is. Next read the attached Swallow et al. (1998) paper, and look at what the heritability values were, also look at the generation time.
Answer the following questions:
1. How do heritability and environmentability differ?
2. What role does generation time have in the whole heritability issue?
3. What does the heritability value mean? What do the heritability values in the Swallow study mean?
