Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
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.
What types of mixtures can be used by gravity separation?
These mixtures must have large differences between densities.
Why are chromosome copied before mitosis?
After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
Why do two nuclei in a divided cell need to be identical?
In a divided cell, the nuclei is identical because it can only reproduce "A sexually" in a sense. Meaning, that if offspring is reproduced, then it must have the genes of the parent cells, but if there is only one parent, then it will have only the exact genes of the single parents, there by being identical.

Do you have to do a paternity test on both babies if they are twins?
Assuming there's no question the babies are identical twins then, no. A paternity test on one will answer the question. However if they are fraternal twins (not identical) then, yes, each must be tested.
Can Tay-Sachs occur in twins?
Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
DNA must remain in the?
DNA is in all your body so your face is based on your structure of your DNA(deoxyribonucleic acid) and no 2 people have the same finger prints so actually there is NO SUCH THING AS I---D---E----N---T----I----C---A---L--- twins or else identical twins would have the same DNA and same fingerprint if you don't believe me look it up in the dictionary of identical=exactly the same no differences

What is developmental variation and environmental variation?
Environmental variation is a change that occurs in your, or anyone's, appearance caused by the environment. Examples are: skin color (like having a tan), a scar, the ability to play an instrument, ability to speak different languages, etc...

How do you incorporate finger prints into an 8Th grade science fair project?
Talk about how they come about. For example, some may find it interesting that identical twins DO NOT have identical finger prints. So, they must not be controlled genetically... Hmmm.
What is the significance of the differences you noted in your answers for 1 and 2?
My answers for 1 and 2 were identical. That in itself must be significant, else what's a heaven for ?
Must the spacing before and after the paragraph be identical?
The spacing before and after a paragraph must be identical.
Howrse made you send a filly twin to your friend?
She is linked to your account by family. She is able to care for an identical horse, but your mare didn't have twins. You must pay for that. :) good luck on howrse!
How are identical twins created or formed?
There are two way twins are formed. Twins can form by two eggs being released by the female and the sperm will fertilize both eggs. The other way twins can be formed is if one fertilized egg divides and forms two eggs.
