Heritability

IMPORTANCE OF ENVIRONMENTAL FACTORS ON DEVELOPMENT The argument of empiricism, founded early in the nature nurture debate, followed by Locke (1632-1704), is the notion that individual experiences lead to distinctive knowledge (Schacter., 2015). These distinctive experiences are how individuals are shaped; followed more recently by Gross (2009, p.89) as “…passive individuals who are shaped by the environment and don’t contribute to it…”; referring to factors such as living conditions and social…

Pigeonpea (Cajanus cajan (L.) Millsp.), also known as Redgram, is an economically and nutritionally important grain legume crop belonging to the Cajaninae sub-tribe of the tribe Phaseoleae under sub-family Papilionoideae of family Leguminosae. Considering the vast natural genetic diversity in the germplasm and the presence of many wild relatives, India is considered as the primary center of origin of pigeonpea (Van der Maesen, 1980). It is one of the hardy, drought tolerant and important pulse…

Hypothesis The research focuses on the relationship between grit – “perseverance and passion for long-term goals” and the educational achievement, in comparison with other factors like personalities (Rimfeld, Dale, Kovas and Plomin, 2016, p. 780). The hypothesis of the research is that grit is a significant prediction of academic achievement. The researchers also want to understand more about the etiology of grit, its genetic and environmental origins. They want to know why individuals differ in…

will respond to diet, exercise, training, and performance. These differences may the deciding factor to which a person becomes an elite performer or remains an average participant. The variation among individuals can be described as heritability and the relative contributions of genetic and environmental factors.…

Altering Personality “To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly” (Bergson). Many individuals assume that personality is something that they are born with, therefore it can never be changed. What these people have not thought about is that people can change their personality due to several factors. Three of the big five personality traits, extraversion, neuroticism, and conscientiousness can all be changed by life experiences, maturity…

disorder is to have a parent that suffers from the same disorder. Even though environmental and relational influences are important, there is a genetic predisposition that underlies this disorder, predominantly in the more severe forms of the disease. Heritability of alcoholism (the genetic component of interindividual variation in vulnerability) is 40 to 60 percent (Enoch & Goldman…

Depression”, written by biotechnologist Adam Alonzi, MDD (Major Depressive Disorder) affects up to 17% of the world's population. MDD, as defined by Mayo Clinic is a chronic, remitting syndrome involving widely distributed circuits in the brain. Heritability of MDD is between 31 and 42%. Epigenetic events that alter the chromatin structure and regulate gene expression are found to be associated with “depression related behavior”, all studies, performed on humans, discussed and reviewed herein…

that 10% of the entire population already has type 2 diabetes (T2D) or has a chance of developing it and 40% of adults are obese. Those who have a predisposition to T2D and diabetes are deeply rooted in genetics. There is about a 70% chance of heritability for obesity and about a 35% chance for T2D; however, these conditions are also caused by lifestyle habits. Many studies have identified potential environmental factors that may cause obesity and T2D; the most prominent being a combination of…

Bouchard & McGue (1990) examined personality traits among twins raised apart and discovered moderate levels of heritability with regard to personality traits. Certain genes have also been associated with social behaviour such as empathy (Ebstein, Israel, Chew, Zhong & Knafo, 2010), however both genetics and environment have been shown to effect empathy levels (Knafo…
