Identical twins are formed when a fertilized egg splits into two, resulting in nearly identical DNA but different fingerprints. Semi-identical twins can also occur when an egg is fertilized by two sperm cells. While they may have similarities, they can have differences in weight, height, personality, and interests. Parents are encouraged to celebrate their individuality. Differences are inevitable due to both nature and nurture.
Identical twins, also known as monozygotic twins, are born when a mother’s single fertilized egg is split into two halves after conception. Since they are formed from the same zygote, their DNA is nearly indistinguishable. Although these twins have the same basic genetic makeup, however, interestingly, they do not have identical fingerprints. Because they are relatively rare, they often attract great curiosity. It is estimated that there are only 10 million couples in the world, which means that around 1 in 80 births is the result of a twin pregnancy.
Recently, researchers have also demonstrated the existence of “semi-identical” twins, who are born when an egg is fertilized by two sperm cells before dividing into two halves. This results in twins having identical genes on their mother, but different genes on their father’s side. However, this form of twin pregnancy is quite rare.
While identical twins have many similarities, there are subtle differences. For example, many couples are of different weights or heights. This can happen due to dietary differences, serious illnesses, or a different connection to the placenta while the twins were still in the womb.
These twins also have personality differences. They may have different hobe interests and one twin may be more outgoing while the other is quiet and shy. In fact, some researchers believe that identical twins will take on the stereotypical birth order characteristics associated with firstborns and younger children, despite the fact that they are usually born within minutes of each other.
Parents of identical twins often contribute to personality differences in their children. While it was once popular to dress them in matching outfits and treat them as part of a pair, many parents are now busy helping their children develop strong individual identities. They encourage their twins to develop a close bond, yet celebrate the characteristics that make each child unique.
While the differences between these twins are hard to figure out, people may think of them as two chocolate chip cookies made to the same recipe. Even if the same basic ingredients are used for the dough, it is impossible to make two completely identical cookies. Subtle differences in size, color and texture are simply inevitable as the position of a cookie in the oven will determine how evenly it is baked. In this way, both nature and nurture contribute to the differences.
