No.
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.
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
Identical offspring are referred to as "monozygotic twins" or simply "identical twins." They arise from a single fertilized egg that splits into two embryos, resulting in genetically identical individuals. This contrasts with "dizygotic twins," or fraternal twins, which develop from two separate eggs fertilized by two different sperm. Identical twins share the same genetic material, while fraternal twins do not.
(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 do not necessarily have to run in the family. Identical twins occur at random, when a fertilized egg splits into two embryos, and this can happen to anyone regardless of family history.
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
Twins can have very similar DNA, especially in identical twins who come from a single fertilized egg that splits into two. On the other hand, fraternal twins are no more similar genetically than any other siblings. Some slight genetic differences can arise due to mutations that happen after the initial egg fertilization.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
If they were not then they would not be called identical twins!
Approximately 30 of twins are identical, also known as monozygotic twins.
Twins are identical because they come from the same egg.
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.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
The same as when you had the first set of identical twins.
Non identical twins.
