Monozygotic

Schizophrenia is diagnosed when at least two of the following psychotic symptoms are present for a substantial period of time, during a one-month period. The symptoms include delusions, hallucinations, the inability to function in major areas such as work, self-care and relationships. Furthermore, symptoms such as disorganised speech, catatonic behaviour, dimisnished emotional expression, in which disturbance lasts for a minimum of six months. (DSM-5 SUMMARY TABLE, PSYCHOPATHOLOGY, by Graham…

Genetic Component It has been known that schizophrenia tends to run in families, and having a family member with it is the highest known risk factor. Children of people with schizophrenia have a 10 percent chance of developing the disorder, and monozygotic twins have the highest risk at 40 to 65 percent chance. In comparison, the risk of schizophrenia in the general population is about 1 percent. Recent research found that people with schizophrenia have a higher rate of genetic mutations.…

Biological theories originally attempted to differentiate among individuals on the basis of certain innate physical traits or characteristics these being influenced by genetic or hereditary characteristics. This was one of Lombroso's largest, and most disproved theories, that individuals with more primitive appearances such as broader foreheads or more prominent chins, similar to neanderthals. More popular today though are biological traits that have the greatest effect on neurological traits…

Ancient DNA • Summary: Ancient DNA is DNA that has been extracted extinct specimens. It can be used to study evolution and genomic consequences of long term environmental change. We can make species un-extinct by using the ancient DNA and then use this DNA to fertilize an embryo. However, the technology to do this is not available yet as no species have had their full genome sequenced. In addition, it is hard to find a surrogate to create an individual from this DNA. Ancient DNA is used today…

Selective foetal reduction The diagnosis of discordant karyotype, with the presence of a serious anomaly in a pair of twins may require termination of the affected foetus. The most frequent anomalies that are indicative for selective termination are central nervous system (CNS) anomalies. Selective termination is a clinical procedure that can be performed in either the first or second trimester of gestation. The technique used depends on the chorionicity of the pregnancy. The perinatal outcomes…

at birth are not only in looks, they similar in behaviors throughout life, good or bad grades, use or non-use of alcohol, use or nonuse of illegal drugs, and type of family they get as adults. The text states that studies "clearly show that MZ (monozygotic) twins were far more similar in the traits of criminality." (Schram, & Tibbetts, 2014, p. 112) What implications do these findings have for the importance of genetics or heritability regarding criminal behavior? Genetics are a factor from…

Genes influence every aspect of human physiology, development, and adaptation. Obesity is no exception. Obesity is a significant health problem affecting all types of individuals; rich and poor, educated and uneducated, Westernized and non-Westernized societies. Over the past 40 years, the prevalence of obesity has more than doubled in the United States and continues to grow at an alarming rate, affecting adults, adolescents, and families. Approximately 66 % of adults and 33 % of children and…

Today is the day of science. Over the past few decades, scientists of all kinds have been debunking centuries old notions of beliefs, tearing them down, and building a new infrastructure based on proven science. One of the biggest notions is that of human nature. What makes us truly us? Is it the way we are nurtured? That was a belief long, and still, used as proof of how we as humans become the people who we are today. However, today is the day of science. Science is finally going for the KO in…

the words “we are what we eat”, but what does this expression really mean? Now it makes sense to me. I also learned how susceptible we are to inherit epigenetic changes due to DNA methylation from our parents. In both videos, they study how two monozygotic twins with the same DNA sequence will exhibit different phenotype and are susceptible to different diseases when they are exposed to different environmental conditions and eating habits. Understanding of…

The purpose of this study is to demonstrate if success in academics or life can be predicted by a person’s degree of grit. The authors of this paper define grit as perseverance and passion for long-term goals as defined by Duckworth of University of Pennsylvania. At the time of this research there seems to be a lot of hype around grit since the department of education in the US and UK have been focusing on increasing student’s grit. Somewhere in the articles it states that previous research has…
