 The Great Debate: Determinism and Free Will
Determinism is a far-reaching term affecting many areas of concern, that most widely and radically states that all events in the world are the result of some previous event, or events.
The first variety of genetic determinism is the rather unsophisticated doctrine of genetic fixity, which holds that the genes of parents inevitably determine the characteristics of their children.
Genetic determinism gains additional support and wider influence from the popular notion that, since we can now establish a scientific connection between one's genes and one's actual and/or potential physical traits (hair and eye colour, disease susceptibility, etc), then we should use this knowledge to restructure the genetic make-up of certain individuals.

 David A. Kirby- The New Eugenics in Cinema: Genetic Determinism and Gene Therapy in GATTACA
Genetic determinism, which is also known as bio-determinism or genetic essentialism, is the belief that human behavior, personality, and physical appearance are determined exclusively by a person’s genetic makeup.
Genetic determinism is a reductionist ideology in that it seeks to explain a complex whole (a human being) in terms of its component parts (individual genes).
Discrimination against the genetically unenhanced presupposes that genetic determinism is the true state of the world and that genetic manipulation actually improves an enhanced individual’s behavior and ability to perform a job; in this case, the genetically enhanced should always perform better than the genetically unenhanced and genetic discrimination is justified.

 GENETIC DETERMINISM AS A FAILING PARADIGM IN BIOLOGY AND MEDICINE--JSWE Vol. 39 No. 2 (Spring/Summer 2003)   (Site not responding. Last check: 2007-10-08)
His view is that genetic determinism, the major component of biological reductionism, is increasingly unable to contend with newer findings of biological complexity and that a new and more holistic scientific theory of living systems is required.
In medical genetic studies (extended families) or in behavior genetics (twin studies), the sample sizes are small, so that error is large in detecting lack of interaction between heredity and environment.
The problem for medical genetic theory is that the common diseases of cancer and of the circulatory system appear to be new; they were not significant causes of death and disability in the early part of the 20th century.

 Background essay on free will and genetic determinism
What plausible versions of genetic determinism seem to explain, then, is not specific acts, or not without help from other factors, but general sorts of behavioral proclivities, personality traits and the like.
We needn't be confusing determinism with fatalism, but on my account we're confusing it with something else, something for which we might more plausibly turn up evidence, in application to particular cases if not across- the-board: namely, psychological unfreedom, or internal behavioral constraint.
This is where I think we can locate at least some of the special problems associated with genetic determinism, as opposed to the various other forms of determinism within the sciences, social or biological.

And the genetic contribution to the traits we value most deeply, from intelligence to compassion, is conceded by even the most enthusiastic genetic researchers to be limited and indirect.
Moreover, given the falsity of genetic determinism, any conclusions a child might draw from observing the person from whom he was cloned would be uncertain at best.
In these cases, the social and legal determination of "who is the parent" may appear to proceed in defiance of profound biological facts, and to subvert attachments that we as a society are ordinarily committed to upholding.

Genetic determinism is dead, and has been dead at least for close to twenty years [3].
Long before we were told there aren’t enough genes to support the genetic determinist view, many scientists have concluded that there are no simplistic explanations for diseases in terms of single genes, because the action of each gene is modified and affected by many other genes.

Contrary to popular belief, people in east Asia are no more genetically susceptible to short-sightedness than any other population group, according to researchers who have analysed past studies of the problem.
I find it hard to see how genetics could possibly explain the disparities between Indians living in Singapore and those living in India proper, or between Israeli students in religious schools and those in ordinary ones.
Arguments that ignore cultural and historical commonalities and differences in order to reduce everything to simple-minded genetic causes are outright invalid and unworthy of being taken seriously, and people who insist on making them despite being repeatedly corrected are simply stupid, certainly far too stupid to be casting aspersions on the "innate" capabilities of others.

 biology - Genetic determinism
Genetic determinism is the idea that genes determine a physical or behavioural phenotype.
Evidence for the genetic influence on phenotypes comes from hereditary diseases, for instance, cystic fibrosis and sickle cell anemia, which are caused by mutations in single genes, and Down syndrome and Klinefelter's syndrome by the abnormal duplication of a chromosome.

 WashingtonPost.com: Human Cloning Isn't as Scary as It Sounds
To think otherwise is to embrace a belief in genetic determinism—the view that genes determine everything about us, and that environmental factors or the random events in human development are utterly insignificant.
The overwhelming consensus among geneticists is that genetic determinism is false.
As geneticists have come to understand the ways in which genes operate, they have also become aware of the myriad ways in which the environment affects their "expression." The genetic contribution to the simplest physical traits, such as height and hair color, is significantly mediated by environmental factors.

In setting out to make genetic research comprehensible to the non-specialist and allay the fears he or she believes it has engendered in the minds of the public—fear of knowing the future, fear of the loss of free will and individuality and fear of discrimination—Peter Little employs an interesting literary device.
An amazingly large number of areas of genetic research and technology are covered: gene regulation, development, twin studies, linkage analysis, genetic variability, selection, gene evolution and pharmacogenetics.
Concepts of race and the genetics of intelligence and behavior are extensively discussed, and the author argues that the latter two areas are worthy of scientific investigation because of the potential to improve education and treatment.

 Glossary Definition: Determinism
Ultimately, if determinism is correct, then all events in the future are as unalterable as are all events in the past.
genetics and human freedom, or unfreedom as it were, illustrates the extent to which genetic determinists place the influence of nature (biology and genetics) over nurture (society and family).
The fundamental premises of genetic determinism are, therefore, 1) that we are victims of our genes and have no ultimate freedom, and 2) that with proper knowledge, we can take charge of our genes so that we are no longer their victim, but rather, are their architect.

Eugene understands that, based on his genetic makeup, he is expected to win every race, that he "was never meant to be one step down on the podium." Ultimately, Eugene comes to see that the unenhanced Vincent is better at being Eugene than Eugene himself.
As was the case with genetic discrimination, the genetically-unenhanced Vincent’s ability to overcome his genetic prophecy calls into question the assumption of genetic determinism.
The opening shot in the film depicts in extreme close-up a slender crescent-shaped object falling to the ground in slow motion; the shot is so disorienting that it is not until later that we learn this object is a fingernail purged by Vincent during one of his bodily scourings.
