This question is not well placed. It should be " a relationship between two organisms in which both benefit is called".
The answer is SYMBIOSIS
Explanation:
Living organisms tend to interact with one another in their natural environment. This interaction are of different types depending on the effect on the involved organisms. One of those interactions is SYMBIOSIS. Symbiosis is a relationship between two organisms in which both of the organisms benefit from one another.
An example is the relationship between the "CATTLE AND EGRET". The cattle provides food for the egret when they feed on the insect parasites on their body while the egret helps the cow get rid of detrimental parasites.
Technically, you need cohesion(water sticking to itself through attraction of hydrogen bonds) to get adhesion(water sticking to other surfaces through attraction of hydrogen bonds). They are rather intertwined. But for this basic answer, it is adhesion.
In this population, what will occur is that there will be no evolution. Mutation is neccessary and important because they provide varitations that can result in evolutionary change. Other factors needed for evolution to occur are migration and selective pressure. <span> </span>
No.As we know that phenotype depends on physical appearance whereas genotype is genetical materials. So person having same phenotype doesn't mean they have same genotype.
