Biological Link versus Emotional link

There is a blur at the point in which our similarities to our parents due to biological link and our similarities to them due to our emotional and cultural link intersect.  To some degree  we are biologically similar to our parents and there is not much we can do about it.  Psychology is a broad subject that is born out of our biological and genetic composition.
How much of our behavior, social skills and ability to learn is predicted by our biological link to our parents and how much of it is simply a result of cultural, social  and religious indoctrination?  http://library.thinkquest.org/C005870/concepts/biologyAndBehavior/Psychology in general attempts to deal with behavior; conformity or non-conformity to the norms passed on to us, not biologically, but as a result of culturization.

Our emotional composition is another point of intersection between science (biology/genetics) and behaviorism.
We are indoctrinated to behave within the guidelines and expectancy of our culture.  In as much as we are biologically made to represent our species, so are we indoctrinated (our brain imprinted upon) to best represent and carry on our emotional (behavioral), social, cultural, family upbringing, religious beliefs, and other codes imprinted upon us.

Does Biological Link equate to emotional link or bond?

We all know that our biological link to our parents is very strong -- the genes passed down from a parent to a child carry a lot of similarities.  A child will have a lot of traits that are biologically "like" many traits of the parent.  A child can have physical attributes that resemble those of the parent.  These attributes can be similar in form (such as a long nose, long legs or a stocky figure) as well as in the way that people carry themselves or similarities in body language.

We are genetically linked to the condition of our parents and predisposed to their genetic attributes, tendencies (for example, it is common knowledge that alcoholism  is genetically inherited) and limitations.  But "to what extent" -- may be an interesting question.   A good, but vague answer would be "to whatever extent" the biological link might be.  The influence of this link is probably impossible to quantify or qualify scientifically, but we could speculate that as a whole we are only susceptible to half the biological influence of one parent and half of the other.  This would make us biologically a whole resulted from the mixture of the two halves -- two parents.

The physical influence dictated by our biological link to our parents is obvious.  The biological influence/similarities in the way that we move, walk, or talk are also obvious.   We don't have to be a medical doctor or a scientist to notice this, although in a physical (biological or genetic) sense there are similarities that a layperson cannot see and can only be determined by trained professionals and techniques in the field of genetics or biology.

Although our biological make-up is extremely important, what about the impact of the biological heritage on us in an emotional and psychological sense?  Are we predisposed to the way our parents are emotionally?  Are we psychologically conditioned or limited to the way our parents are psychologically?  If so, to what extent?  Do we have any control over it?

Is Biological Link a Cause or Consequence?

In an ideal situation the biological relationship that we have with our (biological) parents or children is a consequence/result of a meaningful relationship; one that goes beyond the physical sexual act of an age-fit couple and expands into a fulfilling and loving one.  This is a point at which we transcend from the sexual attraction and urges inherent in our biological condition and enter into the circle of modern, civilized beings organized into what we know as family.  This ideal situation and condition is a reflexion of our historical jorney as humans as we have been conditioned to form families in which our biological link can be identified and protected.

Definition of Biological Link

Biological link (human, in this case) in its broad sense refers to the connection or physical biological relationship between two individuals.  In sum it's the blood relationship or genetic lineage between people.  There are varying  degrees of biological links, depending on the degree of such relationships.  The relationship between parents and children, for example, is known as first degree, siblings second degree, etc.
