Identical Twins or monozygotic twin is defined as one fertilized egg that splits into two embryos; Therefore, sharing 100% of their genetic material. Twins can be born either identical or fraternal. Identical twins have been known to have many similarities including, DNA, Physical traits, habits, and psychological similarities. With having similarities twins have also been known to have just as many differences, some would include how they were brought up and what kind of environment they were brought up in or Nature VS. Nurture. Epigenetic differences to include inherited genes such as schizophrenia or autism. When having twins you are at a higher risk for birth or development complications lower birth weight for the twins or the twins at risk for prematurity. Twin to Twin Transfusion syndrome which is a disease of the placenta, also the twins are at risk of being conjoined which they will be connected to each other.
According to International Journal of Fertility, only about one in eight embryos that starts as a twin is born as a twin ("HEA" par. 2). Naturally having twins will raise your risks and complications from a normal pregnancy. With having twins the two are sharing the same space that one would normally have. Women carrying twins are at higher risk for preeclampsia which is higher protein levels in the urine and high blood pressure if left untreated this could lead to eclampsia. Another complication that is common with twins is gestational diabetes. Gestational diabetes is women that develop diabetes due to pregnancy. Gestational diabetes is common in most pregnancies but even more prevalent in twins pregnancies.
Identical twins have many similarities. The most common being physical similarities, things like height, weight, and eye color. Through Tao's research he concluded that "Fingerprint recognition with identical twins is a challenging task due to the closest genetics-based relationship existing in the identical twins" (1). Tao and his coworkers examined 83 sets of identical twins for this research looking at four different fingers the right index, right middle, left index and left middle. Though the research concluded with being able to identify the difference between the identical twins fingerprints with complex hi-tech equipment they concluded that it was much more difficult and still with only 99.1 %, while the non-identical twins had a 99.99% recognition.
Most twins share mental resemblance as well as physical resemblance. A study recorded by Rosanoff and Associates in 1934 exposes twins vulnerability to situations such as separation. "George and Foster" (5) were two Monozygotic Twins that had been together since birth. When George had been admitted to a psychiatric hospital for schizophrenia Foster started showing signs of depression. Foster had no desire to work or talk to anyone and would just sit there and think until he two was admitted to the hospital. When Foster heard that his brother George was being...
