Use the information in Figure 2 to answer question 6.
Figure 2?Percentage of plants that set fruit as a function of their flower-tube length.
Question 6. What is the relationship between flower-tube length and setting fruit?
Use the information in Figure 3 to answer questions 7 through 10.
Figure 3?The mean number of seeds produced as a function of their flower-tube length.
Question 7. What is the relationship between flower-tube length and the number of seeds produced?
Question 8. Assuming that seed production and fruit set are closely associated with fitness, what do the data suggest about selective pressures on flower-tube lengths?
Question 9. If the variation in flower-tube length in this population were due solely to environmental factors, what would be the expected change in flower-tube length over several generations?
Question 10. What possible experiments can be done to examine whether Agrius convolvuli is the selective agent acting on the length of flower tubes in G. longicollis?
100 60 a 20 120 150 0 30 60 90 0 Flower-tube length(mm)Explanation / Answer
Q6: When the flower tube length is between/ nearly 75-110mm, fruit setting happened between minimum 20 to maximum 100% median value is greater than 50%.
Q7: When the flower tube length is between/ nearly 75-110mm, mean number of seeds ranged from 25-50
Q8: data suggests that selective pressure for longer flower tube length >75mm resulted in good fruit setting, at median value 50% .
Q9: Over several generations flower tube length majorly between 75-110mm will remain same. Becase same phenotypes are successfully fruiting and forming seeds.
Q10: possible experiments can be replace long tongued Agrius convolvuli (mean 102.9 ± 6.7) with short tongued ones if available or if other short tongued hawkmoth species can cross pollinate Gladiolus longicollis, but it can be an obvious failure because short tongued ones cannot collect or deposit pollen, hence long tubed gladiolus will be removed after several generations
