Informative Essay On Twin Babies

The biography Identical Strangers by Elyse Schein and Paula Bernstein is about twins that got separated at birth, and now are finding out there is another person in the world with their exact DNA. They were part of a study on separated twins. It was to see in nature versus nurture which one has more of an impact. (31-32) Identical twins were easiest to study because of their identical DNA. Scientists working on the study placed both girls in a family in which are very similar; therefore, they both have a brother that is a couple years older than them. They find out about the other twin, and Paula is having their

Identical twins look so similar because identical twins have the same genetic makeup, meaning, the same DNA (same nitrogenous bases). This is because by they are fertilized by the same egg, making them identical.

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)

An example of this is fraternal twins. Fraternal twins are twins that were born at the exact same time, but they were fertilized in two different eggs, making them not look identical, like other pairs of twins.

In the video, The Secret Life of Twins, scientist explore the similarities and unique differences between twins--especially regarding their development in contrasting environments. Identical twins fascinatie many people, especially scientist and doctors. Because identical twins are born with 100% of the same DNA, they go on to develop both remarkable similarities and differences. This film encounters some of these amazing human pairs. The film discovers how twins can be identical but grow up to become very different people.

1. What are identical twins? What explains any differences they may develop? Identical twins are twins that develop from the same fertilized egg. Differences in their environment are what explains any differences they may develop.

Monozygotic twins: Monozygotic twins are also known as identical twins. These twins start their life as one egg which is fertilized by one sperm and latter splits into two eggs much earlier in the gestational period. These are very rare and have no link to heredity. But studies reveal that only one of four conceptions of twins is identical. Therefore, it seems likely that any differences between twins will have to be caused by environment rather than by genetics.

The lives of twins are not simply black and white, but very difficult and complex to understand. Many twins get confronted with many problems while growing up. From infancy to young adults, twins have had to endure numerous occasions where they have to explain others about themselves.

There are a number of possible types of these births. These include thoracopagus, the most common, affecting 35% of all conjoined twin births, where the chest wall is shared, and often the heart. Pygopagus is another type, occurring in 19% of all cases, where the twins are joined at the buttocks. Two significantly less occurring patterns are ischiopagus, 6%, connected at the tailbone, and craniopagus, 2%, with a fused skull. Some other commonly occuring types include cephalopagus, with the upper torso and back of the cranium fused, and dicephalus, having two heads and necks connected to one body. Cephalopagus and craniopagus twins are rarely operated on, because the brain is such a delicate organ on which to operate, especially when shared brain tissue is involved. Other types include parapagus, a lateral fusion of the lower half of the body, and omphalopagus, joined frontally at the midsection. Finally there is parasitic twinning, where one twin is dependant upon the other for life, and often one is misformed, lacking organs or fully formed parts (www.twinstuff.com).

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.

When conjoined twins are formed, the female’s egg doesn’t fully split which creates two embryos, their skin and organs can fuse together, but it is very rare. Although the two fetuses will develop

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

I observed a set of dizygotic or fraternal twins, Antonio and James, that had walked in, which were both males. I noticed that they were attached to their mother, which I had considered “normal” when thinking back to when my 15 year old daughter was that age. Even

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

There are many stories of identical twins who were adopted at birth who meet up late in life and discover they share remarkably similar life stories. A study in 1990 found that genetics account for 50 percent of how religious a twin was likely to be. There is also a genetic influence on dental or gum health. Among identical twins, most reported feeling closer and more familiar with their twin than they did to their best friends, even after just meeting them after spending so many years apart.
