Identical twins have the same genotype because they have the exact same genes. Identical twins are formed when one fertilized egg (zygote) splits in two and each of the now two zygotes each develop into different beings. Identical twins are therefore referred to as monozyygotic twins and they have the same DNA.
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.
yes they are... simmes twins form from one egg that is in the process of separating into two eggs or identical twins... but the process isn't finished and that is why they are "stuck together"
Identical twins can share the same placenta during pregnancy, but it is not always the case. In some instances, identical twins may have separate placentas.
Yes.If* two or more organisms are formed from the same original cell, and* all divisions of that cell are by mitosis, and * there is no mutation, then the organisms will be genetically identical (= have the same genotype).Some examples:* human identical (monozygotic) twins * individuals of Hydra, a freshwater coelenterate, formed by budding * plants formed by vegetative propagation, such as budding (e.g. fruit trees in horticulture) and forming stolons (e.g. strawberries naturally)
Yes they do because they are created from the same egg when it splits so they will have the same DNA because they are identical but on the other side regular twins don't have the same DNA because they are from diffrent egg and sperm
Only identical twins from the splitting of the single ovum ( monozygotic) have identical DNA
Twins are identical because they come from the same egg.
do identical or non identical twins share the same placenta
Human identical twins have the same DNA (e.g. identical genotype), but generally have slightly different phenotypes. In this way, you are in fact able to tell twins apart with some study of their features. While their DNA is identical (more or less), they do develop on their own after separation and on through life, making their outward appearances (or phenotype) slightly different. In non-human species, this can be more difficult to discern, but the same does still apply.
The same as when you had the first set of identical twins.
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.
identical twins do. just not the same fingerprints.

Identical twins.
The genotype against the immediate environment and developmental processes. Each organism has a unique environment too. Think about it. Even identical twins are not totally their genotype because they are subject to not only the same environment, usually, but the unique experiences and formative processes of their unique environment.
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.
