Nope. Research has shown that DNA in twins is different, especially in copy number varitations, which refers to when a gene exists in multiple copies, or a set of letters in the DNA is actually missing. These variations are suspected to lead to increased defense against some infections, or vulnerability to others. http://www.nytimes.com/2008/03/11/health/11real.html
Their genes are very similar.
Because the two embryos are the result of a single egg/sperm combination, they have the same genetic origins. They have the same DNA. however, they don't have the same finger prints
Almost! While the sequence begins identical, epigenetics (environmental type factors) appear to cause them to change over time.
What else can I help you with?
Why do identical twins have the same genotype?
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.
Can identical twins be of different sexes?
They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.
Are twins in the same placenta genetically identical"?
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.
What is the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
Does the father contribute to indentical twins?
Yes, the father's genes contribute to the DNA of identical twins. Identical twins are formed when a single fertilized egg splits into two separate embryos, each carrying the genetic material from both the father and the mother.
Identical twins have the same set of?
genes
Can genes of two persons be identical?
The genes of identical twins are identical because the twins come from one egg that has split after fertilization. Fraternal twins are not identical since they come from two eggs but have occupied the mother's womb at the same time.
Can anyone else have the same exact genes that you have?
Yes, identical twins are born with the same DNA.
If two animals have the same genes then are they the same family order class phylum and kingdom?
If their genetic makeup is identical then they are identical twins.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
What do identical twins have the same sat of?
They have the same set of chromosomes, which can be also stated as having the same set of genes.
Two horses with identical genes can be called?
Depending on how they got identical genes, they may be clones (if it was done artificially, and they were born at different times), or if they were born at the same time, they could be identical twins. However, I don't think horses ever have twins.
Why do identical twins have the same genotype?
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.
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
What kinds of twins are there?
Identical and Fraternal There are identical and fraternal. Fraternal twins happen when 2 different embryos start growing at the same time, so you get a brother and a sister or 2 sisters or 2 brothers that are the same age. Identical twins happen when 1 embryo splits into 2 embryos when it is only a few cells big, so both babies have the same genes.
How are twins identical?
Twins are identical because they come from the same egg.
Who are the only people with the exact same genes?
only twins have the same genes (all twins)
