Can twins have different blood types?

Can twins be identical if they have different blood types?

The short answer. Yes. Blood type is entirely determined by DNA, so identical twins pretty much always have the same blood type. But because of the small changes in DNA that can happen in the womb, it's entirely possible for twins to have different blood types from each other.

Is it possible to have twins different fathers?

But you may be left wondering: Can twins have different fathers? The answer is yes, but only in cases in which they're fraternal, as identical twins form from a single egg/sperm combination and thus cannot have different fathers.

GENETICS 1: INHERITANCE OF BLOOD TYPE

Can a woman get pregnant while pregnant?

A double pregnancy, or superfetation, is extremely rare — in fact, there aren't even stats on how often it happens — but it's scientifically possible. We're not saying you should worry about it happening to you, just that you can't say that it's impossible.

Can a baby eat its twin in the womb?

Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple. The fetal tissue is absorbed by the other twin, multiple, placenta or the mother. This gives the appearance of a “vanishing twin.”

What's the golden blood type?

What is the rarest type of twins?

Can two O positive parents make an O negative child?

A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children.

Are Mary Kate and Ashley identical?

Can twins have different eye colors?

The possibility of identical twins having different eye colors is extremely rare. Fraternal twins (developing from 2 separate sets of egg and sperm) however can most definitely have different eye colors as they only share about 50% of their DNA with their twin, just like any other siblings do.

Do twins have the same voice?
