Answer:
94.
Explanation:
If 500 F2 offspring resulted from the cross, approximately 94 plants out of 500 plants have red, terminal flowers. The offspring produced in F2 generation in the ratio of 9:3:3:1. According to this ratio, 281 plants having red axial flowers, 94 plants have red terminal flowers, 94 plants have white axial flowers and 31 plants having white terminal flowers. So by totaling 500 plants are received.
The most common circumference to be expected in this situation is 2 cm.
Since it is given that the original population of oak trees contains acorns with the most common circumference of 2 cm, thus, the same circumference will be favored after 15 generations of stabilizing selection.
Stabilizing selection occurs when natural selection results in stabilization i.e. large number of individuals attain mean or average value for a particular trait. In this process, phenotypes of medium-sized individuals are favored through natural selection.
Since it is already mentioned that the mean circumference is 2 cm in the original population thus the same value will be expected after 15 generations of stabilizing selection.
