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.

Is the DNA in twins the same?
if they share 1 heart then yes they do. but if they have different hearts then they do not
Is the way an orgamism looks and behaves a result of its genotype?
The way an organism looks and behaves is a combination of its genotype and also of the environment. For example, identical twins have the same genome but slightly different environments, which cause differences in each twin's behavior.
Why are identical twins always the same gender?
fraternal twins have two different chromosomes
Can you clone memories also?
No. Cloning only makes what are like identical twins, and identical twins do not have the same memories.
Can two organisms have the same genotype?
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)
Can two brothers with same genotype and blood group share the same DNA lab test?
Only identical twins from the splitting of the single ovum ( monozygotic) have identical DNA
How are twins identical?
Twins are identical because they come from the same egg.
Do identical or non-identical twins share a placenta?
do identical or non identical twins share the same placenta
What is phenoype in identical twins?
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.
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.
Is the DNA in twins the same?
if they share 1 heart then yes they do. but if they have different hearts then they do not
Is the way an orgamism looks and behaves a result of its genotype?
The way an organism looks and behaves is a combination of its genotype and also of the environment. For example, identical twins have the same genome but slightly different environments, which cause differences in each twin's behavior.
Does a genotype determine phenotypes?
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.
Do twins have the same DNA?
identical twins do. just not the same fingerprints.
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.
Which animals are the same?
Identical twins.
Which gender is homozygous?
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
