By definition two children born to the same mother at the same time would be twins. It would be possible that they would not be twins if they were only half brothers, meaning that they shared a father but were born to two different mothers at the same time, or where they shared the same mother and father, but one was carried and born to a surrogate, or both by two separate surrogates and just happened to look very simmilar, though they would share different DNA.
If they did share the exact same DNA and also were not twins one would have to be the 'clone' or the other, meaning that a single embryo was 'conceived' from one sperm and one egg, which was cloned, and each embryo was implanted into a different woman's womb, and were born at the exact same time.
They could just be dogs or another animal that is born in a liter. They're brothers and look exactly the same, but aren't neccesarily twins.
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
They may look alike, but they will never have the same fingerprints, because fingerprints are created by differences of thickness in the dermal layer. It is independent of genetics, therefore, twins will never have identical fingerprints and any similarities between twins fingerprints would merely be coincidental.
No two butterflies are exactly alike due to variations in their wing patterns, colors, and sizes. Each butterfly has unique markings that distinguish it from others of the same species, making them distinct and individual.
Usually but not always. They can even be different sexes. Identical twins are fromed from one fertilized egg which splits into two and so genetically they have the same DNA and are therefore identical. Fraternal twins are formed from two separate eggs fertilized by two separate sperm cells, and are called 'twins' simply because they share the womb during their development. Otherwise, they are no more similar than normal brothers, sisters or a brother and sister.
Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
Identical twins look exactly alike.
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.
No, no one is identical. Even "identical" twins are not exactly alike.
It means that you are brother and sister. If they look exactly alike, you could be twins.
You and your friend or sibling could go as twins if you 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.
Ferternal twins don't look alike, but twins do
Sometimes they do. If they do, they are usually children. Their moms usually dress them alike. Some twins wear the same outfit just in different colors. Then their are twins that don't dress anything alike.
Yes
Fraternal twins.
In his book, Through the Looking Glass, Lewis Carroll describes Tweedledum and Tweedledee as 'brothers'. But as they are so alike, it is reasonable to assume that they are identical twins.
"The twins dressed alike to confuse the minds of their dates." "Humans are like snowflakes, no two are alike."
