The biosphere over laps all spheres
Answer: Linear
Explanation: The DNA molecule could be either linear or circular. Now according to the question, since each enzyme is cutting the DNA at one point only, the circular DNA would make two fragments only. It will look like this image shared below. And if its linear, then only it can make three fragments. The case of both linear and circular DNA is mentioned in images shared below.
It would be completely false to say that both internal and external environments can modify or alter a gene. The correct option among the two options that are given in the question is the second option or the last option. I hope that this answer has come to your great help.
Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant. The fruit color of eggplants is another example of incomplete dominance.
