What would it be like to have a twin? This is a question people often ponder. People often say that they see someone that resembles someone they already know. It is almost like dejavu. “Twin” comes from the German word “twine” meaning “two together” (Nagy 1). Most people automatically think of two people who look just alike when they hear the word “twin”. However, there is a lot more to twins than just looking alike. Twins are the most common type of multiple births. Many think there are only two types of twins, identical and fraternal; they often leave out conjoined twins. Twins are very unique and fascinating individuals because of their similarities biologically, physically, and psychologically. An author from the twin’s network stated that, “A British scientist was the first to say that identical twins are identical biologically and may have come from a single egg” (Nagy 1). He was correct when he made this hypothesis. Identical twins form when a single fertilized egg splits usually one to fourteen days after conception (Wade 53). Identical twins are the same sex, they have the same chromosomes, and are the same blood type. Identical twins also mean monozygotic twins. According to the twin’s network, studies show that identical twins live longer than fraternal twins; they believe this is due to their close communication (Nagy 1). Fraternal twins are the most common type of twins. They are the result of the union of two eggs and two sperm. Fraternal twins can be the same or different sexes (Wade 53). Segal says that, “They are two individuals, no more genetically alike than brothers and sisters that develop from separate fertilizations” (Segal 1). Amazingly, fraternal twins can be conceived at separate times and have different fathers. It seems to be a hereditable trait to conceive fraternal twins. Yet, tendency to conceive conjoined twins may be caused by genetic and environmental conditions (Hunter 1). Conjoined twins are the rarest type of twins. Conjoined twins were once known as “Siamese twins.” Conjoined twins originate from a single fertilized egg so they are always identical and same sex twins. The developing embryo starts to split into identical twins within the first two weeks after conception but stops before completion. A partially separated egg is left of the embryo, and it continues to mature into a conjoined fetus (Hunter 1... ... middle of paper ... ...rities and the same preferences. They also felt an immediate bond upon meeting. Jim Springer and Jim Lewis are twins who were separated four weeks after they were born in 1939, and they were reunited thirty-nine years later. The twins discovered that they had married and divorced women named Linda, married second wives named Betty, and named their first sons James Allan and James Alan, respectively. They both drove the same model of blue Chevrolet, and they both enjoyed the same hobby. They often vacationed on the same small beach in St. Petersburg, Florida, and owned dogs named Toy (Heredity 62). There have been many cases reported similar to this one, such as where twins were separated at birth and when reunited, found that they had astounding similarities between the two. By studying twins who were reared apart, scientists are learning how the forces of nature and nurture interact to make us what we are (Chensanow 69). Many environmental, genetic, and emotional factors are related to the composition of twins. Any types of twin share a relationship that most people will never experience. Twins, whether fraternal, identical, or conjoined, are an amazing phenomena of human life.
Nature is the inherent features of something. Genetics also is a big part of nature. Anais and Sam are identical twins. They were separated at birth and adopted by different parents. Although they did not grow up together they had come to know that they have a lot of similarities. These girls have the same laugh, it sounds the exact same. Anais and Sam both do not like when the shower curtain touches them, and they even have the same favorite drink. Twins have very special bonds that include having very familiar likings and dislikings. They also have most of the same habits and interests. A big thing that is common among twins is that they end up getting the same IQ results and test scores. Some scientist had even shown that twins are more
mothers. Siblings, especially twins, share more than just parents. There are certain things that people have to just learn to accept in life, and the similarities between immediate family can be hard to acknowledge. Every person is a unique individual, but parallelism between family is bound to happen, whether good or bad.
Twins are truly fascinating from the time of separation of the embryo to birth; and still the complexity of twinning is not yet fully understood among the scientific world. Scientists have studied the human body from the time of prenatal development to birth, and still are in awe of the formation of twins. Research in twinning is ever more increasing in this field, leadi...
It is true that identical twins have many similarities, but people tend to ignore their differences. The Jim twins, for example, may
All over the world, there are many different medical cases discovered. There are very rare ones and some common ones as well, we often see them everyday or on television shows. An example of one of these cases would be the Hensel twins,they are conjoined twins.Conjoined twins are very rare, that occur once in every 200,000 live births.Which means that most people in their lifetime will never get a chance to meet conjoined twins. Many people question how to categorize conjoined twins, most just categorize them as humans. A human is just continuity of life to be the same human,while a person is rational, moral and agent. John Locke puts the twins in thought when speaking of the Day-Man and Night- Man, a man with one body with
Twenty years ago, twin births were radically lower, with twins being more frequent than other multiple births. With technology becoming more advanced and people who normally have problems becoming pregnant can use in vitro fertilization, people delaying motherhood, and survival rate increasing; having twin children is not as rare as it was thought to be in the past. Twin birth rates have increased 42% from 1980 to 1994 (Lytton, Singh, & Gallagher, 1995).
My daughter Myla Jane and her cousin Braelyn Jade are different in appearance and attitudes, yet are the same in the things that they enjoy and their daily routine of everyday life. When you look at the two girls, you can’t tell by their looks that they would be anything alike. Although they are a lot different in looks, they do share similarities. When seeing these girls at a back-to-back view, the only things that you would find to be similar are their enjoyment of the same things and their routine they follow throughout the day.
Within his blog, Manly uses the experiences of other twins to strengthen his argument. His twin brother Daniel says: “‘I remember one girl in grade four, who used to tell us apart by the colour of our lunchboxes! That stuff is ridiculous, since the easiest way to tell us apart is to know us.’” I believe what Daniel says is true. Singletons should take the time to know each twin individually, instead of knowing a set of twins as one person. Manly states that this confusion on which twin is who often leads to a difficult environment for individuality to develop. I agree to this as well. In my own experience of being a twin, I have struggled to become myself with my peers, since I am constantly referred to as “one of the twins” or “a
The thought of cloning often terrifies people because they believe there will be copies of themselves rampaging around the world. Individuals often overlook that, “In nature, twins form very early in development when the embryo splits in two. Since they developed from the same fertilized egg, the resulting individuals are genetically identical” (Genetic Science). Scientists who understand the procedure of twin formation, have been using reproductive cloning for decades. According to Devolder, “The genetic material is removed from a donor egg so as to create an empty egg. A cell is then removed from the male’s rep...
Have you ever heard that twins could have completely different personalities, they could be friends, siblings, or possibly even enemies. Author Eric Wright creates a story about a writer who specializes in writing
As I walk through the crowded mall with my sister, little children stare, most adults do a discreet double take, and some bold adults question us outright. “Wow, are you twins?” “Do you know you look the same?” “What’s it like to be a twin?” “Do you have, like, psychic powers, or something with each other?” These are the most common questions twins hear. Almost all twins don’t really mind them and sometimes the attention is cool. Mostly, we just smile tolerantly at each other and answer them as best we can. After all, we don’t really know how to describe being a twin. We have never known anything else. Nonetheless, here we are. So, as a person who might not know exactly what she is talking about, I will try to briefly explanation to the general public the experience of being a genetic quirk.
The last “lot in life condition” is “ you and your spouse have just been told that you are expecting triplets.” Triplets can result from one zygote (an egg fertilized by one sperm) dividing into three. This means that the triplets would be genetically identical. Triplets could also occur if one of two zygotes divided in half. This would mean that two of the triplets would be genetically identical while the third child is considered a fraternal multiple. Parents who are expecting triplets or have triplets can find help from Mother Of Supertwins (MOST), which is a non-profit network founded in 1987 by several mother of triplets who had and continue to have variety of challenges in raising their super twins. MOST provides information, resources,
Sue and Heidi have as many differences as they have similarities. But they do not compete with each other and are like built-in best friends. Sometimes they communicate with one another by an unspoken means, telepathy. Identical twins, Sue and Heidi are a remarkable creation. On the outside they are a perfect mirror image, but, on the inside, they are as different as night and day.
Over the last couple of decades scientist, psychologist, and people have questioned over the idea, and the stereo typical question of nature versus nurture. Using twin studies, scientist have been given the understanding that the environment and heredity influence their behavior development. With using the adoption in twin studies, the doctors and scientists have been able to tell the extent to which the resemblance and families is due to the jeans that are shared and due to the environment that is shared. Because of the jeans that are identical carried by the monozygotic twins, identical twins, there has been a great appeal to most scientists and doctors. Psychologist have been able to link the strong genetic
It is true that identical twins who are raised together have many things in common,
