Question
After wandering around bogs in North Carolina, you get interested in the quantitative genetics of trap diameter in Venus flytraps. You bring several Venus flytraps back to your greenhouse and start breeding them in an artificial selection experiment. The mean diameter of the flytraps you originally brought into your greenhouse is 4 cm. Among the individuals that you selected to contribute to the next generation, the mean trap diameter is 5.75 cm. Upon rearing the progeny of the selected parents, you find their mean trap diameter to be 4.6 cm. Given this information, what is the response to selection (R)?
Based on the information given in the previous question, what is the selection differential (S)?
Given the information presented in the question before last, what is the narrow-sense heritability (h2) for trap diameter in your population of flytraps (round to two decimal places)?
