What are fraternal twins?

Brethren twins are siblings who are conceived at the same time of two separate fertilized eggs. Sometimes they are also called "biovular twins" or "non -identical twins". In fact, it is quite common for fraternal twins to be defined compared to the same twins. The identical twins are two siblings who were born from a single fertilized egg that is divided to form two fruits instead. One of the key features of identical twins is that they look incredibly similar or the same. Also identical twins always share the same sex.

Unlike the same twins, fraternal twins may look quite different as sometimes siblings. In fact, it is common for fraternal twins to be confused for siblings, which simply happened at age. This is especially true in late childhood, adolescence and later in life. In addition, while fraternal twins can be the same sex, it is also possible for a few such twins to consist of one chlaPCE and one girl. This is because the sharing of all their genes as the same twins is shared by fraternal twins on average 50 percent of their genes.

Another term for fraternal twins is the "Dizygotic twins", which is sometimes referred to as "DZ twins" in a shortened period. This simply means that the twins are the result of two zygotes instead of one, as in the case of identical twins. Zygote is a scientific term of a fertilized egg. In the case of identical twins or "monozygotic twins", only one zygot is present at the moment of conception.

Much later in life, it is possible that the same twins will be confused with fraternal twins. This is because the general health, the level of personal care and the lifestyle of a person can change the way a person ages. If two members of a pair of identical twins lead very different lives, it is possible to look more and more than aged. Cosmetic, such as hairstyle, clothing and make -up, can also cause the same twins to look more like fraternal twins.

There are groups that are more likely to produce fraternal twins than others. Dizygotic twins are more common in older mothers, especially women who are struggling after 35 years. They are also quite common in Japan and in some parts of Africa. There is evidence that there are DZ twins, which are often the result of genetic predisposition.
