Biological Genetics and Criminal Behavior Over the of course of the years, different criminologists and scientists have tried to understand the reasons and origins of crime and deviant behavior. What makes a person commit the most atrocious and heinous crimes? This is a question many people try to understand. Many factors affect the actions of these criminals, from biological factors to psychological issues. The big debate among these studies is whether such criminal behaviors are inherited…

“Being gay is a choice” is a phrase that is often used by right-wing conservatives, but what if it isn’t so. Is it possible that the “gay gene” that causes humans to have same sex attraction exists in conjunction with pheromones? It is possible for there to be some genetic factor with pheromones that causes homosexuality at a minor scale compared to heterosexuality. Pheromones in humans have long been a mysterious concept with little evidence to prove, although it is present in other animals of…

Depression has been said to be to be a “common cold of mental health” (Lucknow, n.d.) and this is because of the alarmingly huge number of diagnosed patients that suffer from this mental disorder. It is quoted that more than 350 million people of all ages suffer from depression worldwide. However despite this, many cannot tell the difference between feeling sad or depressed and having clinical depression. This makes the current use of ‘depression’ in some cases pop-psych, that is psychological…

Cloning in its simplest sense is “to make an identical copy of” (“Clone”). However, while cloning is the act of replicating, the word cloning encompasses far more than simple duplication. Cloning involves a wide variety of processes that can be used to produce genetically identical copies of a biological entity. In terms of biology, cloning is the natural process of producing similar populations of genetically identical individuals when organisms such as bacteria, insects or plants reproduce…

complications of type 2 diabetes as well as several pharmacological treatments. Pathogenesis of Type 2 Diabetes
Genetic predisposition contributes to the pathogenesis of Type 2 diabetes as evidenced by a disease concordance rate greater that 90% in monozygotic twins. Environmentally, the most important risk factor is obesity, with 80% of type 2 diabetes patients being obese, and the global incidence of diabetes rising proportionally with obesity rates. Insulin resistance is the decreased…

I found the theories based on traits and Freud's theory of psychosexual development the most interesting. I found the five-factor model of personality interesting because it is made up of five broad traits and efficiently describes how they contribute to a person’s personality; it is not limited or complex, making it easier to understand and see the correlations. Freud’s theory proposed an interesting perspective on personality. He describes personality as having three sides to it: id—present at…

mental disorder that is characterized by frequent low moods. The aim of the study of Nurnberger and Gershon (1982) was to demonstrate that genetic factors predispose one’s development to depression. They studied seven sets of twins, composing of monozygotic twins, which are 100 percent genetically identical, and dizygotic twins, who share 50 percent of their genes. The twins’ concordance rates, or the rate of which the same trait is present in both…

Introduction The NHS defines addiction as “Addiction is defined as not having control over doing, taking or using something to the point where it could be harmful to you.” Addiction is usually thought of as been related to alcohol, smoking (nicotine), drugs or gambling, but in fact can be associated to far more such as, shopping, solvents, internet, mobile phones or even work. Many reasons can be related to why something is classed as an addiction, typically with alcohol, smoking and drugs this…

poor troubled child to the first neurosurgeon to successfully separate conjoined twins in 1987. Dr. Carson never heard of a case like ours. My sister and I would be the world-renowned neurosurgeon’s first craniosynostosis case where the set of monozygotic twins were…

Lee, Lee, Lee, Hong, & Sung, (2010) compared correctly and incorrectly diagnosed twin pairs, in which, the authors found that misdiagnosed dizygotic twins demonstrated remarkable similarity in physicality and weight even exceeding that of true monozygotic twins. Song et al., (2010) suggests that a parsimonious questionnaire used in diagnosing the zygosity of the infant twins would be advantageous, whereas, adding physical or physiological measures would either confound the correct diagnosis or…
