Identify a dependent variable in the experiment represented in Figure 3 A. Identify the control group for the
experiment represented in Figure 4. Based on the data in Figure 4, describe the effect of elevated FGF5 on the
rate of hair growth in culture. Based on Figure 2, if individuals 19 and 20 have another child, calculate the
probability that the child will be affected with FT, assuming that individual 20 has no family history of FT.
