What makes identical triplets?
464582
Either the egg divided twice into four as above, or the egg divided once into two blastomere and then one of those divided again into another two making a total of three.

Hey man..ask both the questions together.Anyways now i will explain you both. Here t means triplet. It means three similar energy orbitals. Others are\nA=Singlet\nE=Doublet\nT=triplet\n\nAlso 2 here dentoes symmetry about the center. i.e 2 are centrosymmetric while one are no. e.g p orbitals being centro symmetric fall in 2 case and sp3 hybrid orbitals fall in 1 case!!

Yes identical twins do have the same DNA. They came from the same egg so they have identical DNA.\n\nIdentical twins\nIdentical twins occur when a single egg is fertilized to form one zygote (monozygotic) which then divides into two separate embryos. The two embryos develop into fetuses sharing the same womb. Depending on the stage at which the zygote divides, identical twins may share the same amnion (in which case they are known as monoamniotic) or not (diamniotic). Diamniotic identical twins may share the same placenta (known as monochorionic) or not (dichorionic). All monoamniotic twins are monochorionic. Also note that any monochorionic or monoamniotic twins are identical twins. This condition does not occur in fraternal twins.\n\nThe later in pregnancy that twinning occurs, the more structures will be shared. Zygotes that twin at the earliest stages will be diamniotic and dichorionic ("di-di"). Twinning between 4 to 8 days after fertilization typically results in monochorionic-diamniotic ("mono-di") twins. Twinning between 8 to 12 days after fertilization will usually result in monochorionic-monoamniotic ("mono-mono") twins. Twinning after 12 days post-fertilization will typically result in conjoined twins.\n\nIn placental species, twins sharing the same amnion (or the same amnion and placenta/chorion) can cause complications in pregnancy. For example, the umbilical cords of monoamniotic twins can become entangled, reducing or interrupting the blood supply to the developing fetus. About 50% of mono-mono twins die from umbilical cord entanglement. Monochorionic twins, sharing one placenta, usually also share the placental blood supply. These twins may develop such that blood passes disproportionately from one twin to the other through connecting blood vessels within their shared placenta, leading to twin-to-twin transfusion syndrome.\n\nMonozygotic twins are genetically identical (unless there has been a mutation in development) and they are the same gender. (On extremely rare occasions, an original XXY zygote may form monozygotic boy/girl twins by dropping the Y chromosome for one twin and the extra X chromosome for the other.) Monozygotic twins generally look alike. Fine physical details such as fingerprints will differ. As they mature, identical twins often become less alike because of lifestyle choices or external influences.\n\nThe likelihood of a single fertilisation resulting in identical twins is not a hereditary trait.[citation needed] The exact cause for the splitting of a zygote or embryo is unknown.\n\nHuman identical twins can behave as differently as any other siblings (a matter of much interest to psychologists). They develop their own individual personalities, enabling them to be identified as individual persons. Many identical twins spend most of their time together (especially as children), so people often assume that they will behave alike just as they look alike; however, this is not the case. Twins are unique individuals that establish their own individual likes and dislikes. There are usually obvious signs of differences when the identical twins are observed separately or together.\n\nIdentical twins have identical DNA but differing environmental influences throughout their lives affect which genes are switched on or off. This is called epigenetic modification. A study of 80 pairs of human twins ranging in age from 3 to 74 showed that the youngest twins have relatively few epigenetic differences. The number of differences between identical twins increases with age. 50-year-old twins had over three times the epigenetic difference of 3-year-old twins. Twins who had spent their lives apart (such as those adopted by two different sets of parents at birth) had the greatest difference. (Fraga, et al., 2005).\n\nSome monozygotic twins are known as "mirror twins" or mirror image twins. These are identical twins with opposite features, that is, one may be right-handed a

The children will not be "twins" (they will likely not look the same, though they may look similar in the way siblings do). This is because during meiosis, the genes in each haploid are random, from both parents.\n\nFor example, if both twin brothers had a dominant gene for black eyes and a recessive gene for green eyes, one twin might pass on a black eye gene to his child, while the other might pass on a green eye gene.

In identical twins one is is a natural clone of the other.  If science ever really created an artificial clone, it would have the same right to life as anyone else.  But I do not expect a responsible scientist to do that.  What they're up to is creating stem cells for use in curing a variety of diseases.  Those who oppose this are phonies about their respect for life.

Identical twins have identical DNA. They come from the same fertilized egg, which had only one complete set of DNA in the first place. That fertilized egg and its single set of DNA split to form twin embryos-each with its own set of DNA, identical to the other. One small quibble: the DNA sets will be identical, unless one fertilized egg's DNA mutates. Such mutations, however, are normally so tiny that DNA analysis can't detect them

Because DNA is identical, and it is the unique genetic code from which we each emerge. With twins - DNA is the same, as are the chromosomes, but the proteins, cells and organs which are transcribed/expressed from that DNA may vary slightly.

They are part of a set of triplets :-)

Multiple births come from two sources.  First, sometimes more than one egg is released in a single cycle.  If multiple eggs are fertilized, fraternal twins (or triplets or whatever) result.  That's why you get so many multiple births with fertility drugs--they often force many eggs to be released at once to improve the odds, or implant multiple fertilized eggs in the hope that at least one will live.\n\nIdentical twins and triplets are grown from a single egg and a very energetic sperm, which strikes the egg so hard that it tears apart into two or three fragments, each of which becomes a baby.  These babies all came from the same egg/sperm combo so they have the same genetic information.  That's also why you don't see identical siblings more than triplets.  There's only so many pieces you can tear an egg into with one impact.\n\nIncidentally, conjoined twins also come from a sperm tearing the egg apart.  If it doesn't quite separate, the pieces of the egg will form into two babies who are attached where the egg didn't tear.

A very good question from your nephew\nNature provides us with the natural form of clones:\nidentical twins share the same genetic makeup and even\ndeveloped in the same uterus. Nevertheless, their\nfingerprints are not identical, though similar. The\nformation of fingerprints is partly the result of a\nstochastic process.\nThe ultimate shape of fingerprints are believed to be influenced by environmental factors during pregnancy, like nutrition, blood pressure, position in the womb and the growth rate of the fingers at the end of the first trimester. \n\n\nSo identical twins and clones are similar and they have similar but not identical finger prints.

It is genetic. The first source gives the information on a chromosomal difference and second and third sources are on brain differences, and the fourth source is on two identical twins raised in the same household with what appears to be different gender identities.

Never, just like their DNA, and the shape and structure of their eyes, their finger prints will not be the same, some time there are born identical twins to parent that look alike 99.9% but the only thing that make them different is that .1% and their DNA and finger prints, it is just a divine way of God creating his creatures,

Hi! I'm the mother of identical twins.  Here's some facts:\n\n1. Identical twins occur when one fertilized egg splits.  It's a random act of nature and is not impacted by family history, age, ethnicity or fertility drugs.  Every pregnancy has a 1 in 250 chance of being identical twins.  Identical twins have the exact same DNA.\n\n2. Fraternal twins occur when the female produces two eggs and both are fertilized.  It can be influenced by family history or fertility drugs.  Advanced age or certain ethnicities also increase your chance of fraternal twins.  Fraternal twins are essentially brothers/sisters who happen to be born at the same time.  \n\nHope this helps.

HEY ARESEANTLERS! Let me clue you in on this. You can have the exact same DNA but still have different fingerprints. Fingerprints can't change DNA assumptions. By the way, identical twins DO share the same DNA because they come from the same sperm and fetus. Sperm carries DNA and so does the fetus. So how will the twins be different from each other?

No. Identical twins are genetical clones but they have absolutely two diffenrent souls, different characters.\nIf God will ever allow people to be cloned, then He will also give these clones souls - because the clones are real people, with real needs, real life - and real soul.

First, clones have been around for a long time - they can occur naturally. Identical twins or triplets start off with the same DNA and are considered clones of each other. There are many species of animal, including humans, where twinning naturally occurs.\n\nSome species, of both plant and animal, have been bred for so long to contain the same genetic material (useful for genetic studies) that each generation has the exact same DNA as its parents. While regular reproduction occurs, since the source material is the same, there ends up being no genetic variation, except for mutation.\n\nAs for artificial cloning, that has been developed in the past two decades. In 1997, Scottish researched announced that they had successfully taken genetic material from an adult ewe (female sheep) and inserted it into an egg cell that was implanted into another sheep who gave birth to the clone (Dolly the sheep), in a process called 'somatic cell nuclear transfer'. Since Dolly, several other mammals have been cloned. Because the transfered adult nuclei don't always take well with the hosting egg cells, there are many egg cells that don't develop clones than there are successful cloning attempts.
