Toxell et al. (2003) examined the heritability of an adaptational response to exercise in rats. They were looking at whether the ability to increase endurance due to training was heritable. Which of the following is an appropriate statement based on their results?

Question
QUESTIÓN 36 Toxell et al. (2003) examined the heritability of an adaptational response to exercise in rats. They were looking at whether the ability to increase endurance due to training was heritable. Which of the following is an appropriate statement based on their results? 700- y = 0.43x + 236 R= 0.36 600- P< 0.007 500- 400- 300- 200- 100- -100- -100 100 200 300 400 Mid-Parent Values (m) O a. 43% (coresponds to slope) of the response to training in offspring can be explained by genetics O b. Heritability of this trait is very low. OC. There is an inverse correlation between parent and offspring response to training. O d. H2 (broad sense heritability) = 0.36 (coefficient of correlation) Offspring Values (m)
