What Twins Can Teach Us About Nature vs. Nurture
Why Twin Studies?
Twins provide a valuable source of information for health and psychological research, as their unique relationship allows researchers to pull apart and examine genetic and environmental influences. Twin study findings have been influential in detecting and treating various diseases and psychological disorders. How are they able to do this? Twin studies allow researchers to examine the overall role of genes in the development of a trait or disorder. Comparisons between monozygotic MZ or identical twins and dizygotic DZ or fraternal twins are conducted to evaluate the degree of genetic and environmental influence on a specific trait. If MZ twins show more similarity on a given Nurture research on twins compared to DZ Nurture research on twins, this provides evidence that genes significantly influence that trait. However, if MZ and DZ twins share a trait to an equal extent, it is likely that the environment influences the trait more than genetic factors. For example, Figure 1 presents MZ and DZ twin correlations for several physical and psychological characteristics. As shown in the figure, MZ Nurture research on twins, on average, are twice as similar as DZ twins for these characteristics, suggesting that genes influence the development of these traits. In addition to traditional twin studies, children-of-twins studies are a particularly useful way to examine genetic and environmental influences on traits and disorders and their transmission across generations. Given this, their cousins through that aunt or uncle are like genetic half-siblings. As these cousins typically live in different households, this relationship allows for a unique perspective into possible interactions between genetic influences and environmental factors. Results from twin studies may suggest that a particular trait or disorder has a genetic component, but this does not provide information about the location of this gene or genes. Nevertheless, twin designs and methods are extremely useful for understanding the extent to which Nurture research on twins and medical disorders, as well as behaviors and traits, are influenced by genetic factors. This information can then be used to develop better ways to prevent and treat disorders and maladaptive behaviors.
Therefore, the study concludes that the majority of academic achievement is due to genetics in both identical and fraternal twin sets. This. The insight we gain from studying twins helps us to better understand how nature and nurture work together. For well over a century, researchers have compared. For their study, the researchers examined data from twins and their parents who are part of the ongoing Michigan Twin Neurogenetics. Scientists have long used the study of identical twins to examine the effects of nature versus nurture, as the accepted view has been that. Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits. Unknowingly, Bernstein and Schein had been part of a secret research project in the s and '70s that separated identical twins as infants and. Church attendance, educational level, and six conservatism scales were the subject of a multivariate behavior-genetic analysis by Truettet al. (Behav.
When the twins were finally reunited at the age of 39 in , they discovered they both suffered from tension headaches, were prone to nail biting, smoked Salem cigarettes, drove the same type of car and even vacationed at the same beach in Florida. Genes can help explain why someone is gay or straight, religious or not, brainy or not, and even whether they're likely to develop gum disease, one psychologist explains. Such broad-ranging genetic effects first came to light in a landmark study — Minnesota Twin Family Study — conducted from to , which followed identical and fraternal twins who were separated at an early age. Segal described the groundbreaking research on Aug. Researchers at the University of Minnesota, led by Thomas Bouchard, launched the landmark study in Over the course of 20 years, they studied pairs of twins — 81 pairs of identical twins twins who developed from one egg that split in two , and 56 pairs of fraternal twins twins who developed from two eggs fertilized by two different sperm. The Jim twins were probably the most famous set of twins involved in the study, but other pairs were equally fascinating. One pair of female twins in the study were separated from each other at 5 months old, and weren't reunited until age 78, making them the world's longest separated pair in Guinness World Records. The Minnesota study resulted in more than individual studies focusing on different medical and psychological characteristics. In one study, the researchers took photographs of the twins, and found that identical twins would stand the same way, while fraternal twins had different postures. Another study of four pairs of twins found that genetics had a stronger influence on sexual orientation in male twins than in female twins. A recent study in Sweden of 4, pairs of twins has replicated these findings, Segal said. A study that was part of the larger Minnesota study found that genetics plays a larger role on personality than previously thought. Environment affected personality when twins were raised apart, but not when they were raised together, the study suggested.
