It’s a plus-plus, also known as mutualistic relationship. Our intestines provide a habitat for the good bacteria and in return the bacteria fend off bad bacteria from harming us.
The parallel evolution of flowering plants and pollinators represents a case of coevolution. It may lead to different types of natural selection.
<h3>Disruptive, stabilizing, and directional selection</h3>
Disruptive selection is a type of natural selection that favors extreme phenotypes (in this case, flowers too small or too big).
Stabilizing selection is a type of selection that leads to decreased genetic variation (in this case, all red flowers to attract pollinators)
Finally, directional selection is a type of natural selection where an extreme phenotype can be favored (in this case, taller plants to be noted by bees).

Answer:
platypus and a duck has similar DNA.
Explanation:
There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.
