Heritability

A genotype is known as the complete genetic makeup of a given organism. Consequently, a genotype is the one responsible for the phenotype of an individual. In eukaryotes, a single genotype is capable of expressing more than one phenotype (observable characteristics). This possibility is because genes can go through lots of differentiation processes like mutation, changes in gene expression and frequency. So, mutations play a significant role in variation. For example, DNA can be affected by the…

Using your own words, describe what is meant by ‘scientific racism’ and ‘heritability’ and provide an example of each, drawing on the material presented in Investigating Intelligence. This essay will define and explain the terms ‘scientific racism’ and ‘heritability’, and further it is going present an example of each from the book “Investigating Intelligence” to support and give better understanding of these psychological terms. Scientific Racism is a psychological term, technique or…

influences were observed using twins. The study found that in terms of personality there was a moderate positive correlation with heritability. This means that it is possible, but not certain, that genes can influence personality. In regards to intelligence, the study found that with increasing age, there is a more positive correlation between intelligence levels and heritability. In other words, older adults seem to be more correlated with their families in regard to intelligence than when they…

environment that a child is brought up in (White). It is the whole “monkey see, monkey do” scenario. This is called social learning; it was discovered a long time ago so it is unclear as to why it was not taken into account while researching the heritability of behavior. Regardless, it is now known that environmental differences result in the development of different behaviors. While language and behavior are not entirely dependent on genetics, there are some traits that are almost entirely due…

These surprising and “wild” results still leave many questions unanswered, such as why the percentage of intelligence due to heritability is so high, as well as leaves many psychologists skeptical. “In social science, it's rare that we can explain even 10 percent of the variance of a trait,” explained Dr. Robert Plamin, a psychologist at the Pennsylvania State University whose own…

The debate on the extent of the effects of nature versus nurture has existed for centuries. Nature describes human genetics and heritable traits, and nurture expresses how humans are raised and their surrounding environment. Many psychology scholars disagree over the comparative contributions of genetics and experience. Plato alleged that both personality and intelligence level were hereditary, while Aristotle asserted that human’s knowledge and traits came completely from experience (Myers…

From an evolutionary perspective of psychology, human emotions likely served a practical purpose essential for survival, thus being adapted through the generations by the process of natural selection. Essentially, emotions solve adaptive problems. Not surprisingly, most problems from an evolutionary perspective predominantly concern either survival or reproduction, although different emotions have distinct solutions to a variety of situations. For example, the emotion of fear may have the…

Wonseleah Yleah Professor Hayes CENG 106-03 03 December 2016 Childhood Obesity With nearly one third of children overweight or obese, the number of overweight and obese youth has been increasing dramatically in recent decades, and it’s becoming an epidemic. Although the definition of obesity has changed over time, it can be defined as an excess of Body Fat (BF). A child is obese when he or she is well above the normal or healthy weight for his or her age and height. According to OALib…

22.2 months), the stranger, the twin’s mother, and two undergraduate students that rated each of the twins during the observations. Each infant was assessed at home. In all but one of the seven situations, only situation 1 (warm up) suggested heritability. This is due to the chronological order of the situations. The unexpected presence of the stranger, then the interactions ( the warm up period) proceeding his immediate arrival to the home most likely enhanced the differential responding of…

On the off chance that IQ is genetically decided and a steady component of behavior, then there has been more advancement of these genes over under 100 years of time in the US than we see over any two groups of current human. That is unimaginable. Once more, IQ does not carry on pleasantly as a genetic characteristic. The revelation of a quality or set of qualities that would underlie IQ has not happened. In some current reviews, IQ is thought to be extremely mind-boggling and the aftereffect of…
