Genetic Determinism of Human Character Essay - 640 Words

Human character and behaviour are not only shaped by the genes that encompass the individual’s genotype. Human character comprising mainly of personality, sexuality, morality and intelligence are the products of genetic determinism as well as external environmental factors. â€Å"Single genes can have surprisingly strong influences on particular aspects of behaviour.† (Frank., 2009) Genes build the phenotype of humans as well as the underlying genotype. Competition between cultural genes leads to varied success of genetic determinism. It can therefore be said that learnt traits such as those espoused within a specific culture, can produce what may seem to be the genetic genotype of an individual. Genes are not always advantageous in the†¦show more content†¦This being said, there is not a specific gene for a specific trait. Traits are inherited although without the environmental influence they are not expressed in an individual’s phenotype. Contrariwise, you can find genes under a microscope. They exist in nature. The same cannot be said of either personality or intelligence. Behaviour, therefore, depends on the interaction of multiple gene sequences with environmental influences. It has been found that 30-70% of one’s personality traits are genetic and the rest are environmental. (Gil, 2010) Genes are found in the DNA of a human and genes are expressed through phenotypes (The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment (Google, 2014)). Each person has a human genome sequence and the gene segments within ones genome have certain effects on the body. Gene segments contain hereditary information and therefore certain genes can be and associated with particular behavioural traits. Genes and the environment influence behaviour, as there is constantly an interaction between the two. Genes, via their influences on morphology and physiology, create a framework within which the environment acts to shape the behaviour of an individual. The environment can affect morphological and physiological development; therefore behaviour develops as a result of ones interactions with the environment. Genes create the scaffold forShow MoreRelatedExplaining Diversity Essay1090 Words   |  5 Pageswith the continuance of culture through time, the principles have diverged human experience into thousands of different cultures. In Biology as Ideology, the argument of genetic determinism arises; ones genetic makeup and other biological factors are the main determinants of individual behavior. This theory is greatly reliant on a culture looking for a direct cause and effect relationship between the genetic makeup of humans and social ability. Like this belief, the Origin Myth in Mala nowskis MagicRead MoreDiscussion on the Determination of Self Essay777 Words   |  4 Pagesdirection and outcome of his own life, is a slave. However many philosophers and thinkers have pondered this over the years, and some believe that when we believe we are presented with choices we are being deceived, and as B.F Skinner said, ‘human beings.. are not free, because all men are really puppets or robots. Man is a meat machine.’ He argues that as a puppet, we have no will of our own: our movements are entirely under the control of the puppet-master who pulls the puppetRead MoreFree Will vs. Determinism Essay1716 Words   |  7 PagesSo was your decision based off of free will or was this decision predetermined? To fully understand whether your actions resulted from free will or determinism, we must first define each. Determinism is the idea that everything happens due to a cause or a determinant, which is something that can be observed or measured. To put it simply, determinism does not mean that the future can be predicted. Rather, it is a prediction of the possible outcomes that may occur. To help predict outcomes we use factsRead More Causal Determinsim1448 Words   |  6 PagesCausal determinism is the concept that preceding causes give rise to everything which exists such that reality could be nothing but what it is. Science depends on this idea as it aims to find generalisations about the conjunction of certain causes and effects and thus hold some power of prediction about their future co-occurrence. However, in human interaction people assume each other to be responsible for their acts and not merely at the whim of causal laws. So the question which troubles philosophersRead MoreThe Controversy Over Free Will And Determinism1354 Words   |  6 PagesIt has been debated over centuries whether us humans have control over our destiny, and if we are really able to decide on our own. The controversy between free will and determinism has been argued about for years. If we look into a dictionary, free will is define as the power given to human beings to be able to make free choices that is unconstrained by external circumstances or a force such as fate or divine intervention. Determinism is defined as a philosophical doctrine that every event, actRead MoreHuman Beings as Being Genuinely Free Essay781 Words   |  4 PagesHuman Beings as Being Genuinely Free To be able to answer this question successfully we must first understand what is meant by the term genuinely free. By this do we mean to have limitless freedom where each choice is our own or rather freedom within certain boundaries? There are of course many different views which consider the extent of our freedom and what being free really means, ranging from ultimate, unlimited freedom to us having absolutely no freedom.

However, since scientist’s production of the first recombinant DNA and its hybridization in 1972 (genome.gov) genetic determinism has taken on a new set of circumstances. â€Å"Since the 1970s, numerousRead MoreThe Different Ways Of Which Freedom Can Be Compatible With Determinism1334 Words   |  6 Pages FINAL EXAM 1-Discuss the different ways in which freedom can be compatible with determinism. Answer: According to (Consider Ethics text book on page 224), Freedom and determinism can be compatible with Simple Compatibilism, which according to David Hume, he claimed that ‘’all the puzzles and disputes about free will result from sloppy and confused use of language. Therefore, if we think carefully, and avoid verbal entanglements, thenRead MoreAnatomy Of Violence : The Biological Roots Of Crime908 Words   |  4 Pagesneuroscience or biological psychology employs the principles of brain pathology to the study of human behavior through genetic, physiological, and developmental operations, as well as, the brain’s capacity to change with experience.
