The difference between twins and twins

Human beings have a wide variety of characteristics that make them unique, such as personality, physique, tastes, among others. However, when it comes to genetics, there are cases where two people They can look exactly the same, which leads to the differentiation between twins and twins.

Twins

Twins are two individuals that develop from the same egg fertilized by a sperm. These are called identical twins o monozygotic since they have the same genetic information and, therefore, have an identical physical appearance.

Twins

On the other hand, twins, also known as bivitelline twins o dizygotic, develop from two eggs fertilized by two different sperm. This means that they have different genetic information and, therefore, do not share an identical physical appearance. Twins can be of the same gender or different genders.

Physical differences

Although twins have identical physical appearance, they are not completely alike. This is because, even if they have the same genetic information, environmental factors and epigenetics can influence their development and cause small differences in their physical appearance. On the other hand, twins can have large physical differences between them due to their different genetic information.

How can they be detected?

• Twins are detected by ultrasound during pregnancy, since they share an amniotic sac and a placenta.
• Twins, on the other hand, have two amniotic sacs and two placentas, which allows them to be distinguished using an ultrasound, and also due to the fact that they tend to be more physically different from each other.

Conclusion

In summary, the main difference between twins and twins lies in their genetic information and physical appearance. While twins have the same genetic information and identical physical appearance, twins have different genetic information and can have large physical differences between them.
