Biological factors are something that contributes hugely to the formation and maintenance of relationships- whether it is romantic, friendly or family related. Many researchers have conducted studies in which they have attempted to try and explain the link between biological factors and human relationships.

Through this it helps the couples to feel closer and more bonded. One of the main criticisms of this experiment was the complexity of the researched relationships and how since they didn’t consider other factors that might affect the results, therefore resulting in the possibility that it could be unreliable. However if looking at just this one aspect, this biological factor can be considered to have an influence on human relationships both mother child and
