Who Is Nina Smarter

Identical twins are many times seen as genetic reproductions representing variations from twin to the other twin and are created because of environmental factors (Cervone & Pervin, 2010). Since identical twins share identical genetics, his or her personality seems to also share similarities. Moreover, the environment can impact fraternal twins, resulting in fraternal twins personalities and his or her characteristics similar to each other. For example, identical twins. Some research shows twins that are raised in the same residence have little differences from those who are raised in a different home.

Twins often like the same things and think alike, so it is inevitable that they will become close. There will always be a shoulder to cry on or someone to have your back. The other twin is always pushing the other to do their best. When one of them is sick, the healthy one can bring home the homework and notes for that day.

Table 3-1 examines the correlations between selected characteristics for the identical twins separated at birth and the twins raised together. When compared to each other, they both have very similar brain wave activity, blood pressure and heart rate in the physiological characteristics. The Raven intelligence test was very similar, but the WAIS IQ displayed a bit of difference when compared to the other comparisons made. Personality wise, they typically had similar personalities at the same rate as twins raised together. Psychological interests were off a little bit, but still very similar. The twins that were separated at birth had less similar psychological interests compared to the twins

3. What is the difference between MZ and DZ twins? The difference between MZ and DZ twins is MZ twins are monozygotic twins which means that they are identical because they have mono (one) placenta. The DZ twins are dizygotic twins, they are fraternal twins and did not share the same placenta. DZ twins are not identical. MZ twins are genetically identical, DZ twins have only 50 percent of their genes in common. Some studies have shown that identical (MZ) twins raised apart and have never met have nearly identical behaviors. Identical (MZ) twins are much closer than fraternal twins. I personally have seen this because I am the mother of MZ twins. My boys are identical in every way. They are actually mirror image identical twins. Their hair is exactly opposite in the way that their hair lays in the back of their head. One has a cow lick in the front on the left side and the other has a widow’s peak on the left side in the front. One has a freckle on the back of his neck on the left side and the other has a freckle in the exact spot on the opposite side of his neck. When the boys started rolling, one rolled left and the other rolled right. When they started crawling, one crawled forward and the other backward. Their teeth

Twin studies are a mainstay of the nature verse nurture debate because they allow researchers to conduct “natural experiments” on human beings. When researchers try to determine the relative importance of genetics and environment with regard to a certain condition, they have a hard time because they cannot generally get people with the same genes. This is where twin studies come in. Twins studies are part of the method used in behaviour genetics, which includes all data that are genetically informative. E.g. siblings, adoptees, pedigree data etc. Researchers use this method to estimate the heritability of traits and to quantify the effect of a person 's shared environment (family) and unique environment (the individual events that shape a life) on a trait.

Identical twins may share the same DNA make up and grow up in the same household, yet they have very distinct personalities. On the other hand, twins that may have been separated at birth, find that years later when they meet up for the first time that they have very similar character traits and experiences. Researchers have been trying to figure out for years if DNA or environment has a bigger factor in determining a twin’s personality. When researchers try to determine how personalities are developed, they often look to twin studies to determine if DNA or life experiences are influential in personality development.

In reading stories about identical twins my point of view is easily understood. Various types of psychologist have analyzed the study of identical twins. It shows that individuals with the same genetic make-up can be totally different, when it comes to personality. Nurture promotes the twins to grow up as separate individuals. Its a lot better if a twin has his or her own personality rather than the same exact personality of the other half. I think this great debate weighs heavier on the nurture side. As a child my parents, and sibling overshadowed my genetic make-up. No matter how much I thought my physical traits made me behave. It did not affect me more than the things that I had seen and been exposed to. The more things that I had seen around and experienced made me the person that I am today. If my genetic make-up was totally different, to a certain extent, I am sure that I?d behave the same way that I do presently. There are exceptions to that. For instance if I were six foot five and one hundred and ninety pounds, I?d most likely be in the NBA and be really rich. I think if I was really rich and in the NBA I wouldn?t have the same worries that I have today. Even if before I were in the NBA I would have lots of attention and have a lot more confidence. So to an extent I would change a little if my genetic make-up were different. In a sense, genetic make-up is just a competitor to the environmental factors

Twins, share a bond that no parent, child or sibling relationship can ever compare. There are two main types of twins, and these include: monozygotic (identical) twins and dizygotic (fraternal) twins, and they are compared by their emotional, behavioural, and cognitive similarities. (Robert Plomin, 1997). According to Social Issues Referencing, 2007, whereas Identical twins are formed from a single (mono) zygote and are genetic “carbon copies”, fraternal twins develop from two (di) separate zygotes, as a result of two eggs being fertilized by two sperms independently. (Social Issues Referencing, 2007, para. 8)

Comes into the soap opera as the daughter of notorious tavern owner Georgie Zamdela. Georgie was incharge of the underworld in Horizon Deep and many people who watched Isidingo referred to him as the gangster or mafia of the deep. Nina took over his role as the gangster and her cunning looks made you fear her even on the other side of the television screen.

Twins are born with the same genome and epigenome but the environmental factors that they are exposed to bring a difference in their epigenome. As twins grow they experience different things and they make distinct life choices which can make twins so different from each other.

Throughout history, across all cultures, people have been fascinated with twins. In addition to interest in the close emotional ties and biological similarities that twins may share, reports of special twin languages and twin extrasensory perception (ESP) help people to explore ideas of what it means to be human. How similar or different are they to each other? How important are genes and environment for development? Because identical twins share all of their genes, it is the environment—rather than genetics—that accounts for any differences between them.

Identical twin studies are most useful in determining genetic influence on intelligence. Since the identical twins share the same exact genes, the straightforward comparison of intelligence can display if this human trait is truly heritable. Similarity of intelligence scores between identical twins supports the genetic influence on intelligence. According to Myers (2007),

Twins are sought to be an interesting set of individuals and many questions can surround the theories of twins and their IQ, mental states, and the psychological tolls it may have on them and their families. Many parents can barely handle a singleton and would find twins birth a more challenging surprise. Some people believe that the IQ and mental state of the twins could come from their birth rate which at many times is low or the family dynamic for which the twins are raised. Many twins depend on each other in order to learn and develop which could have some advantages and disadvantages among their growth. Singleton children may have older or younger siblings or surround themselves with a group of different types of age groups and grow from there, but twins are at times more of a loner and like to stay among each other which have been my experience with my twins. Identical twins as oppose to fraternal also has an effect of the psychological and IQ of each of them. Fraternal twins are more like singletons for the most part because they do not share a egg where as the identical twins( which is have) develop differently and have a closer bond because they share the same egg and were actually a single egg that was split into two eggs.

There are two types of twins. One type of twins, called identical twins, is exact clones of each other. They share the same DNA and were made from a single split egg. More research as been done regarding these types of twins as they are the more remarkable kind. Since they are a genetic match, nature plays the

For years I have been fascinated by that mysterious quirk of nature called twins. In my family, there are several sets of identical twins, and I have always concentrated on their similarities. I did not realize that identical twins also have many differences. My identical twin cousins, Sue and Heidi, appear to be perfect mirror images. They love to dress alike. They can feel each other's pain. They sound alike and can complete each other's sentences. But upon taking a closer look, I have found that they are as different as day and night. Aside from Sue and Heidi's outward characteristics, they possess several distinguishing traits that allow them to be viewed as two separate, independent
