They do look different! Even identical twins, with identical DNA, are different. Most have a slight difference in height and weight. Many people have a difficult time telling them apart because they are focusing on the wrong things. If someone looks only at the hair, they may not see that their faces are slightly different.
There are many twins that don't look alike. They are called fraternal twins.
Yes, non-identical twins are often referred to as fraternal twins. These twins develop from two separate eggs fertilized by two different sperm cells, resulting in genetic differences that can make them look less alike than identical twins.
No, fraternal twins come from two separate eggs fertilized by two different sperm, resulting in genetic variation, whereas identical twins come from the same fertilized egg, resulting in identical genetic makeup.
Generally fraternal twins are more common. For fraternal twins to occur twins must diverge, but differentiate upon becoming separate entities. Identical twins are rarer, in which the two siblings are of the same gender and are exactly alike upon birth. Rarer so are conjoined, or "Siamese" twins. This occurs when twins are born partially or extremely fused together. There is only a 25% survival chance for a conjoined twin. Most were only connected by gristle and flesh, and could have been easily separated easily, were they in modern society.
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
Identical twins look exactly alike.
Children never look exactly alike unless they are identical twins. Even identical twins often have some differences in their looks, their fingerprints differ, and they may have scars or other features that look different.
You and your friend or sibling could go as twins if you look exactly alike!
It means that you are brother and sister. If they look exactly alike, you could be twins.
Ferternal twins don't look alike, but twins do
Fraternal twins.
There are many twins that don't look alike. They are called fraternal twins.
freternal twins are born on the same day but don't look alike.
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
They can look alike but, they don't look exactly alike. No two of any species are exactly the same.
Twins can look alike due to sharing the same genetic makeup from their parents. This genetic similarity can result in similar physical features, such as facial structure, eye color, and hair color, making twins look alike. Additionally, twins may also share common environmental factors that can contribute to their similar appearances.
It means 'fraternal twins', the kind that don't look alike. The kind that look alike are called 'gemelos.'
