All You Need To Know About Identical Twins DNA

Do you have a twin brother or sister and wondering: do twins have the same DNA? In most cases, people are unable to distinguish individuals who are identical twins. You can confirm this aspect if you are one of the twins or come across a family with such kids. The two have a similar appearance, height, voice, and same level of IQ.

Also, you may find that their body works the same way. For instance, you may notice that the two go for a short call at the same time. This aspect is impressive and surprising. But why does this happen? Here are some things you need to know about identical twins:

Identical twins have this name for a reason. One, they look the same. Their similarity originates from conception. After fertilization, an egg splits into two to form duo fetuses. This aspect means that you and your twin sister or brother came from one egg and sperm. So, you’re not a product of different sperms on one egg.

Their DNA composition is the same

The genetic composition is different in many people. Your genetic makeup depends on what you shared with your mother and father. Even though you share the same parents, your DNA may differ in some aspects. This aspect is due to being products of different sperms and eggs.

For identical twins, the case is different. The identical twins DNA composition is similar. As noted above, the two come from one egg. They have the same components in their DNA that make them perform tasks almost at the same level.

They differ from fraternal twins

Unlike the case where identical twins have identical DNA, fraternal twins are different. This type of twins comes from separate eggs and sperms.

During fertilization, a woman can produce two eggs at the same time. The eggs receive different sperms that fertilize them. In some surprising cases, you may find that the fraternal twins have different fathers. So, each of them gets a different DNA component.

They can donate organs through transplant

Maybe you’re wondering whether identical twins have identical DNA makeup. If this is the case, can they donate organs to one another? The answer to your question is yes. Identical twins can donate organs to one another. These twins are the perfect match for donating organs to one another. Their identical DNA means that they act as “spare parts” for one another. Hence, if you have a twin brother or sister and need a kidney transplant, they are perfect for donating.

However, you might not know whether your identical or fraternal twins. For this reason, conducting identical twins test to determine your twin zygosity with DNA labs such as PaternityUSA.com.
