FXS can lead to a range of social and cognitive impairments, and it is one of the most frequent genetic causes of intellectual disabilities (Bagni, Tassone, Neri, & Hagerman, 2012). Individuals with FXS tend to exhibit hyperactive traits, attention deficits, language development difficulties, communication problems, visual-spatial processing deficits, and social anxiety (Reiss & Hall, 2007). Behavioral symptoms may include aggression, tantrums, self-injury, and repetitive behaviors (Newman, Leader

everything the body needs, especially proteins (Kugler, 2014). Our genes are passed down to us from our parents, having two copies of each gene. Those genes are found in the different strands in our DNA, which is what makes everyone’s DNA is unique. Behavioral genetics examine the role that our genes play in our behavior. The impact of heredity (nature) is the physical looks and characteristics passed down (inherited) from our biological parents. Heredity includes someone’s height, skin color and health

mapping the human genome. The sequencing of the human genome is the largest undertaking in biological science, and is a huge achievement in the scientific community. The project was completed in 2003 and gave scientists the ability to read nature’s genetic blueprint of a human being. Those scientists and medical professionals who were excited about the HGP saw clearly how genomics would advance medicine. Genomic findings have advanced the diagnosis and treatment of many diseases. “Already, doctors

Over the years, many studies have been conducted in order to answer the question if a person’s genetic makeup and environmental factors contribute to behavioral issues. This is an example of the nature vs. nurture debate. Nature has to do with the genetics while nurture has to do with environmental factors (Plomin, et al, 1994). An individual’s genetic code is made up of 46 chromosomes, 23 from each parent. It can be argued that an individual can be pre-disposed to violent tendencies and

and influence our resulting personality and other existing traits. We are, as Myers (2012) continuously asserts, biopsychosocial beings (p.124). These aspects of our existence work in accord to actuate the developmental potential written into our genetic code. Where I think there is a deficiency in the theories proffered, in attempt to answer the Nature vs. Nurture issue, is in the lack of consideration for the spiritual reality in which we exist. Theories are bereft of mankind’s spiritual nature

In a section of Ethics: Theory and Practice entitled “Biological and Genetic Determinism” Thiroux and Krasemann explain: “Biological determinism is best exemplified by Charles Darwin’s theory of natural selection, which he presented in his most famous work, The Origin of Species. Darwin (1809-1882) believed that various species in nature evolve at different stages in the history of the world and that only the fittest survive. For example, even though some prehistoric animals (I.e. dinosaurs) were

IQ and Heritability According to studies conducted by researchers, it has been shown that genetic factors affect the IQ of a person, and specific genes that take part in influencing the IQ have been identified. The studies have also proposed that performance is affected by genetic factors. However, it has not been clear whether the genes that shape the IQ are the same genes that influence test scores and grades. The high heritability of intelligence proves to be a difficult subject because it may
