Dr. Guzman is studying the mean red blood cell (RBC) count of a population of guinea pigs living on.a mountain in Peru. The guinea pigs in this population live along a steep altitudinal gradient with some pigs living at extremely high mountain elevations with low oxygen concentrations while other live at low elevations near the base of the mountain where oxygen concentrations are high. The high elevation pigs have a far higher mean RBC count than the pigs living at low elevations. Higher RBC count allows for more efficient uptake of oxygen in low oxygen environments. Dr. Guzman wants to know if the variation in RBC count is due to genetic variation or environmental variation. She takes 20 guinea pig babies born to low elevation parents and places them at high elevations to be raised to adulthood and vice versa. She then observes the mean RBC count of these individuals. (Tip: Define Vg, Ve, and Vp in the margin) Examine the data presented in the figure. Which of the following is true given these data? Population 1. Born to high elev. parents Born to low elev. parents Raised at Raised at high low elevation elevation Mean RBC Count
