Essay On Heritability

Superior Essays
Can a Heritable Trait Be Changed? This myth comes from a very common misconception that heritability is determined by genetics, which is false in itself. Heritability explains variation in traits, but does not address how traits are passed down from parent to child. This is an estimate of to what degree genes contribute towards the presence of a trait. A change in heritability can change without any genetic change occurring. Charles Darwin’s theory of evolution gives examples of how traits change as a species evolves. In biology, evolution is the change in the inherited traits of a population from generation to generation. Heritability overall is usually traced back to family members, cultural beliefs, diseases, or traumatic events. The myth is often believable because people associate heritability with an inherited trait, when they are completely different. So it is proven that a heritable trait can in fact be changed. It is a common belief that “heritability” and “inherited” are the same thing, which is not actually the case. People believe that if a trait is heritable you can’t change it, and most don’t even …show more content…
The research shows different ways that traits can be affected and the ways that they can affect the child after it is changed since it came from the parent. There were examples of studies that tested IQ from parents to children and how the scores varied and why they varied. Traits can be greatly influenced my genes as well as slightly changed by environmental factors. In addition to the environment’s ability to change a trait, people also have the ability to change personality traits in themselves with a fair amount of time and effort. All in all, the myth that because a trait is heritable means it can’t be changed is proven to be a myth from the numerous examples stated as well as many other

    “On Human Nature” Refutation David Hull’s “On Human Nature” is an article written to oppose human nature. Specifically, it challenges human evolution as the cause of universality/commonality of human traits. The case made in the article utilizes the logic behind Charles Darwin’s theory of natural selection: evolutionary changes come via the generation of variation in each generation and differential survival of individuals with different combinations of these varying traits. The central thesis of “On Human Nature” is that any common set of traits that people share is due to chance as opposed to the inner workings of evolution.…

    Biologically traits can be passed from generation to generation. Physically traits may show up while others are still there but not presented physically. People have underlying prejudices that have been formed through unconscious, norms that were instilled in them from their family, and other environmental experiences. Socially the view of race as a whole was imparted on everyone from the day we were born and how we were brought…

    Both of her parents are also slim and always have been. It could be argued that Cheryl is slim due to the genes she inherited from them – nature. It could also be argued that Cheryl is only slim because she attends the gym regularly and eats a balanced diet - nurture. From a young age Cheryl’s parents encouraged her to attend dance classes as a form of exercise. Did this contribute to her choosing to maintain a healthy lifestyle?…

    An ongoing debate in psychology known as nature vs. nurture, questions whether the hereditary material or the environment of an individual impacts their physiological development that shapes who they are. John Locke, a philosopher viewed development as a “tabula rasa,” meaning blank slate. He believed that the genetic makeup of a person did not play a role in their development, but rather the experience of a person’s life is what determines their development. On the other hand, naturists believe that the genes and hereditary factors we inherit at birth, influences who we are; they claim that humans possess an innate and genetic predisposition. Although the coding of genes in humans determines physical attributes like eye color, height, and…

    Building on the work of Huxley, Tinbergen (1963) formulated four questions to tap into how organisms were structured and why they evolved the way they did (p. 411). Evolutionary questions typically fall into the why group as they address the ultimate levels of inference. Conversely, questions of ontology seek developmental answers for observable changes. Psychology is primarily concerned with the individual level of analysis, but in the case evolutionary psychology the theoretical and practical lines are much more blurred. This paper will provide a roadmap for the main positions held by evolutionary psychology while criticizing some of its key assumptions and theoretical blunders.…

    . These hypotheses do not suggest differing biology, they merely suggest that ancestral traits were chosen for to maintain survival against the selective agent. The general public misunderstands inherited ancestral traits to be biological variation amongst race groups. In Clarence Gravlee’s article, “How Race Becomes Biology: Embodiment of Social Inequality” he wrote, “The central argument is that the race concept is inadequate for describing the complex structure of human genetic variation.…

    Inherited traits put growth and development into action in not only individual organisms but also the evolutions of species over time. Humans wouldn’t have evolved to who we are now if it wasn’t for inherited traits. In fact all species have adapted and evolved to be unique and distinct. For example a hummingbird that has adapted to have longer bills to be able to reach inside a flower to get nectar. Hummingbirds could die out from having short bills so they evolved throughout generations.…

    Introduction The inspiration for my research was found in two articles: “Mapping the Bilingual Brain” by Chris Berube and “Can You Make Yourself Smarter?” by Dan Hurley. The interaction between Berube and a multilingual 5 year old in his blog inspired me to further my research away from the home environment of where things are originally learned, and into the foundation of the role of genetics in an individual’s personality and behavior. I thought it suffice to assume that the little girl must’ve learned multiple languages from her family, which made me think in the simplest terms: “What else do we inherit from our parents?” Dan Hurley’s article was the first stimulus article that brought up the topic of genetics and other factors that contribute…

    The nature vs nurture debate began with Frances Galton in 1865. Frances Galton wanted to look at the debate of nature vs nurture from a different perspective than ever before, and get evidence from actual twins and families themselves. He began his studies by taking interest in twins who were very alike in adulthood and youth, who were educated together for many years, and find out whether they ended up growing to be unlike one another, and if so, what the family thinks the main causes were that caused these dissimilarities. Galton states that “In a few of these not a single point of difference could be specified. In the remainder, the colour of the hair and eyes were almost always identical; the height, weight, and strength were generally…

    The human experience starts at birth and ends with death. One of the greatest debates throughout the era of modern psychology is nature vs. nurture. Understanding what makes a person the way they are can be controversial. Some argue that a person’s genetic makeup strictly dictates who that person will become, while others believe the way they are raised, no matter their genetics, makes them who they are. Both the environment a child is raised in and their genetic makeup will dictate the individual’s intelligence.…

    The phenotype is often not influenced in one way or another; there is a range oh phenotypes that result from an environmental factor influencing the genotype. For example intelligence, a child could be equipped with the genetics to be smart (high IQ) but without an enriched environment as a child, learning and intellectual growth can be slowed down or stunted. For instance, I was in an orphanage until I was two-years-and-four-months. I was not in an enriched environment, which greatly slowed down my learning language, reading and even hand-eye-coordination skills. When I was adopted a program was implemented to make up for this loss, however, there were permanent deficits as a…

    This was without taking into account social and cultural factors that can be transmitted to and placed upon children just as easily as genes. Behavior supposedly “unlike many physical traits, can be directly transmitted from parents to offspring, independently of genes” through the 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.…

    The impact of heredity and environment is indeed undeniable and the two are significantly intertwined. The development of the emotional characteristics depends on the influence of the environment, but the physical genetic manifestations such as color of skin, eye color, height, etc. are maintained. The emotional characteristics for the most determine the shaping of the individuals’ disposition and character. As expressed by Collins et al. , “Estimating the effects of heredity versus environment ignores the potential for malleability, even in characteristics heavily influenced by heredity.…
