What are the 2 kinds of twins?
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.
Who are clones fraternal twins or identical twins?
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
How do you know if two twins are identical or just fraternal twins that look a lot alike?
(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.
Are identical twins more common than fraternal twins?
it was 1/250 just for twins, but identical is more common then futurnal
Why wont the babies look the same if identical twins have babies with identical twins?
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
What are mirror twins?
Mirror image twins are identical and have mirror image differences but are genetically identical which means they have the same DNA. A set of mirror-image twins will have similarities like a mole. One twin would have it on his left arm while the other would have it on his right. Another common feature is one twin being left handed, while the other is right handed. For male twins, the swirl of hair crown is often in the opposite direction.
What is a mirror image?
If you are mirror image twins it means that you are also identical twins. Mirror image twins are created when the fertilised egg splits quite late (around days 9-12), any later and twins can be co-joined.Mirror image twins have small mirror image differences but are actually genetically identical; this means you have the exact same DNA!Some parts of the body are commonly mirrored; mirroring of appendix or heart or other internal organs is rare. We have some examples of our own mirroring:We are opposite handed (Tash is left-handed and I am right)We tend to have mirror image dental problemsPeople often have two different size feet; with us the opposite foot is largerWe look very similar to each other but the resemblance is even stronger if we stand facing each other (as though in a mirror) rather than side by side. Or get both of us facing into a mirror and things start to look very confusing.Our finger prints don't seem to conform to being mirror image - instead they are nearly identical (only one pair of fingers has any major difference)However enviromentally things can make an overall change to the behaviour of mirror image twins however not much will likely change genetically.Thank You Twins Realm for the Supporting Information above.
Can a sonogram produce a mirror image of a baby to where it looks like twins?
of course not! A mirror image would have to have one image of the baby and the second image precisely behind it- and you know that cannot happen in a real uterus! One single image of a baby cannot mirror a second one to the side of it as in fraternal or identical twins. Look in a mirror and move your arms. Does not the arm move preciely in the reflection the same way you are moving it? it may look like two arms to you but its one!!

What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Why identical twins are similar?
If they were not then they would not be called identical twins!
Why are identical twins identical and fraternal twins are not?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
How are twins identical?
Twins are identical because they come from the same egg.
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
If I had identical twins 3 years ago what are my changes of having another set of identical twins?
The same as when you had the first set of identical twins.
Do identical twins have identical footprints?
No.
