Yes.
It is possible for identical twins to have identical DNA, but very often that is not the case.
Twins are identical because they come from the same egg.
Yes, it's possible for a mutation in the chromosome to produce otherwise-identical twins with opposite genders. But generally no, identical twins have the same gender. (but fraternal twins have different genders just as often as any siblings)
do identical or non identical twins share the same placenta
Well there are cases of identical septuplets. Like identical twins, identical septuplets are all born looking identical and of the same gender only difference is there are 7 children not 2
The premise of the question is flawed. Unless they are identical twins, siblings DO NOT receive the same genetic material from their parents. Normally, children receive 50% of the genes of each parent to create a new 100% combination. So you and your sibling have both inherited 50% of your father's DNA, for example, but you didn't get the same identical 50% as your sibling unless you're identical twins.
The same as when you had the first set of identical twins.
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, Esau and Jacob were not identical twins. They were fraternal twins, meaning they were born from the same pregnancy but did not have the same genetic makeup.
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.
In the case of identical twins, a single embryo divides into two completely separate and genetically identical embryos. Each embryo continues to grow and develop individually, but with the exact same genes as the other.On an interesting side note: Children of identical twins are genetically as closely related to their parent's identical twin as they are to their identical twin parent. Genetically, both twins are the parent of the other's children. Also, their children are genetically half-siblings.
identical twins do. just not the same fingerprints.
