If all this time you are quite familiar with identical and not identical twins, have you known that there are still various other types of twins? Yes, two of which are often considered the same are identical twins and mirror twins. In fact, these two types are clearly different, you know. In order to better understand how to distinguish it, refer to the following information.
How can identical twins and mirror twins occur?
Each type of twin certainly has a different formation process. Similarly, identical twins and mirror twins.
Identical twins
The term identical twin actually comes from the process of the formation of the fetus while in the womb. These twins are called monozygotes, because they come from one egg and one sperm that is the same. Supposedly, the cells that have fused to develop into one zygote after fertilization.
But in the case of identical twins, the fused egg and sperm actually divide into two zygotes. These two zygotes, then grow and develop into two prospective babies.
Because identical twins are formed from one egg and one sperm are the same, then most likely they have genetic and physical characteristics that are very similar to sometimes difficult to distinguish. That's why they are called identical twins.
Twin mirror (mirror twins)
Mirror twins are the type of twins that form when one egg and one sperm are fused during the fertilization process. Just as the process of forming identical twins, cells that have fused into these mirror twins will also divide into two individuals.
Only difference, the process of fertilization in mirror twins occurs very slowly or not simultaneously. This process will last around nine to twelve days after conception.
Uniquely during this time, prospective twins who are developing in the womb will grow asymmetrically or upside down. In other words, these type of twins will look opposite each other like they are in a mirror.
So what is the clear difference between the two?
Indeed, it is quite difficult to tell which twins are identical types and which are mirror twins. Because the two types of twin children really look similar and almost no difference. However, of course there are still special characteristics that distinguish them, such as:
Identical twins
Although the genes that twins have are identical because they come from one egg and sperm, but actually they are not exactly the same.
If you pay close attention, there will be a number of things that distinguish the two, even if only slightly, not even so clearly. Whether it's hair color, face shape, location of moles, and so on.
Quoted from the Verywell Family page, differences in identical twins may still be influenced by environmental factors.
Twin mirror (mirror twins)
While for mirror twins, as the name implies, the most visible distinctive sign is the twins are like the shadow of a mirror reflected by one another. This is what distinguishes it from identical twins.
For example, one of the mirror twins has a dimple on the left cheek, then his brother will definitely have a dimple on the right cheek. Another example, if the first brother has a birthmark in the right hand, then his brother certainly has a birthmark in the left hand.
This also applies in the habit of movement that is often done. If one of his brothers is left-handed, usually the other brother will be more normal in using his right hand.
In a nutshell like this, whatever the shape or placement of body parts or signs in the body, it will appear opposite when the two mirror twins face each other. As if, they were a mirror reflection from his twin brother.
This condition is believed to occur because the brain part of mirror twins works in an unequal manner. That is, the first child may be more dominant with the right brain, while his twin brother is more dominant on the left side. That is why, then both of them show different characteristics, but they are opposite.
