With identical twins, one egg (zygote) from the mother is fertilized by one sperm from the father, and then very early in development the embryo splits and two fetuses grow. Spontaneous division of the zygote into two embryos is not considered to be a hereditary trait, but rather a spontaneous or random event.
If the zygote splits very early (in the first 2 days after fertilization) they may develop separate placentas (chorion) and separate sacs (amnion). These are called dichorionic, diamniotic (or 'di/di') twins. While all fraternal twins are 'di/di', this occurs 20 - 30% of the time in identical twins.
Most of the time in identical twins the zygote will split after 2 days, resulting in a shared placenta, but two separate sacs. These are called monochorionic, diamniotic ('mono/di') twins.These twins are very similar genetically, and share a single afterbirth.
Very occasionally, twins will also share the same sac (fluid cavity). In about 1% of identical twins the splitting occurs late enough to result in both a shared placenta and a shared sac. These are called monochorionic, monoamniotic ('mono/mono') twins.
What else can I help you with?
If you are an identical twin do you share a bag of fluid inside the mothers womb?
That depends on the type of twins. Fraternal twins usually have separate amniotic sacs. Identical twins usually share the amniotic sac.
How twins and triplets develops?
Where one cell splits into 2 or 3 durning the early age of pregnancy
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.
If most children look different then their parents then how are identical twins able to be produced?
When a single embryo in a mother's womb splits into two separate embryos early on in embryonic development, identical twins are created. Because the two twin embryos originate from the same single embryo, they will have extremely similar, if not identical, physical appearances and emotional actions when they are born. Identical twins are "identical' because they are created from the same original embryo during development inside the womb, not due to who their parents are.
Do identical twins have the same finger prints and DNA at all?
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
What is the difference between idetical and non idetical twins in the way they are found?
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
Why are there differences between identical twins?
Although Identical twins look the same and share the same DNA, there are some differences between the two do to there environment and way of life as they develop. However, one way to distinguish between the twins from birth would only be by their finger prints. In other words, identical twins finger prints are different from birth because of there movements within the mothers womb and what they are touching within her womb before they are born.
Why dont identical twins have the same fingerprints?
Identical twins may have similarities in their fingerprints due to their shared genetic code, but they will not have the same fingerprints. This is because fingerprints are influenced by factors during development in the womb, such as the position of the fetus and slight variations in the womb environment, which can lead to differences in their fingerprints.
Is the DNA from identical twins identical What about fingerprints?
There are differences in both DNA and fingerprints.The Claim: Identical Twins Have Identical DNA
How two baby's are born from one mother at a time?
They are known as 'twins'. Identical twins are when 1 fertilised egg divides and each half develops separately in the womb, sharing the same genes. Non-identical twins are when two eggs are fertilised by two separate sperms.
Are identical twins always the same size and birth weight?
Identical twins may not always be the same size and birth weight. Factors such as position in the womb, nutrition, and other environmental influences can lead to differences in size and weight at birth.
Non-identical twins are called?
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
