Twins and twins: biological and psychological differences

The difference between twin brothers and twins generates a lot of confusion for those who are not familiar with the subject. Even Some believe that the two words are synonyms for twin brothers.. Well, nothing could be further from reality.

Let’s solve this little confusion debunking some myths, clarifying the difference between twin brothers and fraternal twins. First we will define each of the two classes of brothers.

The twin brothers, too known as monozygotic, univiteline or identical twins, are those that originate when a single sperm fertilizes a single egg. This zygote (the egg, together with the sperm) divides in two, forming two embryos with the same genetic load. Resulting in two identical siblings born at the same time..

The twin brothers, also known as twins dizygotic, biviteline or fraternal, are those that are produced by the fertilization of two eggs by two different sperm. Thus, The result is two brothers who may be similar or very different, who are born at the same time..

Physical differences between twins and twins

One of the biggest headaches for those who want to differentiate twin siblings from fraternal twins is the physical differences or similarities between siblings. Twin brothers are most of the time “identical”, that is, they practically do not differ. This is because they share 100% of the genetic load. If they have any physical differences, it is due to external factors, such as scars or different hairstyles.

Twin brothers look as much alike as two ordinary brothers. They may have differences in size, skin tone, build, etc. In certain cases, twin brothers can be very similar, because they share more or less 50% of the genes, but never identical.

Do twins have the same fingerprints and blood type?

In the case of blood type, twins have exactly the same blood type because they share the same genetic load, while twins could differ in their blood type.

On the other hand, twins share many characteristics, but fingerprints are not one of them. Identical twins do not have the same fingerprints because they are not just genetically determined. The pattern of the fingertips is formed by intrauterine forces during the gestation period.

So twins are not 100% identical. There are certain differences, many of them imperceptible to the naked eye.

Psychological differences between twins and twins

Both twin brothers and twin brothers have a very special and particular bond between them.. Both types of siblings tend to be much more attached to each other than siblings born at different times. After all, twin brothers were born and raised together, so their bond is unmatched.

As for their personalities, it will depend on the type of upbringing. In the case of twin brothers, they usually have complementary and even dependent personalities.. It is as if the jobs are divided between both, one may have more motor skills and the other more social skills.

For twin brothers, their personalities will be different or similar depending on how similar they are physically. You must also take into account upbringing and the particular relationship between siblings. Twins tend to have a more similar personality than other “common siblings.”but not as much as the twins.

It may even be the case that twins invent a particular language to communicate with each other (It can also happen between common siblings, but it is less common). This special language is known as cryptophasia. It is for this reason that sometimes twins take a little longer to speak than other children.

Therefore, Both twins and twins can share some hobbies, tastes and forms of social behavior. Definitely, twins and fraternal brothers share many characteristics in common. Especially in relation to the psychological section.

Thus, it is important to recognize the differences between the two terms. Depending on whether they are twins or fraternal twins, there will be characteristics that are the same or different.such as the probability of sharing a certain disease.
