In 999% of cases boy/girl twins are nonidentical However, in some extremely rare cases resulting from a genetic mutation, identical twins from an egg and sperm which began as male (XY) can develop into a male / female pair Identical twins are the same sex as each other and look very alike Nonidentical, or fraternal, twins This type of pregnancy occurs when there areThis is a list of multiple births, consisting of notable higher order (4) multiple births and pregnancies Twins and triplets are sufficiently common to have their own separate articles With the use of reproductive technology such as fertility drugs and in vitro fertilization (IVF) such births have become increasingly common This list contains only multiple births which have some claim
Can Identical Twins Be Different Sexes
Identical twins boy and girl possible
Identical twins boy and girl possible- yes they can be identical, mad I know BUT there is a lady Ange on the AMM She has b/g twins was told they were ID all through pg and then they were born one girl and one boy and she was very surprised; Twins of different genders are universally accepted as a sound basis for a clinical determination that boy and girl twins are not identical However, in extremely rare cases, boy and girl twins can stem from the same fertilized egg Twins, who stem from the same fertilized egg, are called monozygotic twins
Do you think they will fall for it??Boy/Girl Monozygotic (Identical) Twins Identical twins are always the same gender because they form from a single zygote that contains either male (XY) or female (XX) sex chromosome In the past, there have been a few reported cases of a genetic mutation in some male twins where one twin loses a Y chromosome and develops as a female The term "identical twins" is generally used as a synonym for "monozygotic (MZ) twins" Both terms assume that that the twins developed from the same fertilized egg (zygote), have identical DNA, and therefore look identical But, as explained here, identical twins do not always look exactly the same And male/female twins certainly don't look
Check out this link When twins are fraternal, two eggs are fertilized at the same time, so it is possible that you still get a pair of samegender twins even though they aren't identical More on that in a moment Identical Twins If you've got boy/boy or girl/girl twins, you may have identical twins The trick is determining whether boyboy twins or girlgirl Even though sesquizygotic twins are very rare, the risks of genetic problems in one of the sesquizotic twins are very high One of the sesquizygotic twins recorded even had ambiguous genitalia which made it difficult to tell whether the other twin was a boy or a girl
It is safe to assume that if twins born are of different sexes, 9999% of the time they are going to be dizygotic or fraternal twins and not identical twins Khushboo Kirale Hi, I am Khushboo KiraleThakker, a marketing specialist turned homemaker and mom of four (1 elder daughter and triplets—all boys)Answer (1 of 43) Usually not Because if so, they would have different sex chromosomes (one will have XX and the other XY) Identical twins develop from a single zygote that later splits in two They have the same genes and usually look very similar They are In the case of identical twins, the fertilized egg splits in two In the case of identical triplets, the egg may split just once into three or it may split twice (where the egg splits first in two and then one of the two splits again), resulting in three embryos with the same general DNA characteristics Monozygotic triplets are always the same sex, either all boys or all girls
Babies from twin pregnancies are more likely to suffer from birthrelated complications than those from singleton pregnancies Fraternal and identical twins can be Young Brisbane twins, a boy and a girl, have been identified as only the second set of semiidentical, or sesquizygotic, twins in the worldThey checked the placenta and yip id They called polar twins I believe and are extraordinarily rare indeed 0
Fraternal twins can be boy/boy, boy/girl, or girl/girl Identical twins are the result of one fertilized egg splitting The split usually happens around days 4 or 5, after the placenta and sac have started forming Which means the two babies end up in the same sac, sharing the same placenta Identical twins are always boy/boy or girl/girlHow common are identical twins? These are the possible sex combinations A set of boy/girl twins Can only be fraternal (dizygotic), as boy/girl twins cannot be identical (monozygotic) Two boy twins Can be either identical or fraternal (monozygotic or dizygotic) Two girl twins Can be either identical or fraternal (monozygotic or
Boy and girl twins are always fraternal, nonidentical or dizygotic They are formed from two individual eggs which are fertilised by two separate sperm A Fraternal twins, like a boy/girl pair, form from two different eggs fertilized by two different sperm, each with its own set of sex chromosomes Fraternal twins can be boy/girl, two girls, or two boys So no, your boy/girl twins are not identicalSo my husband and I assumed identical twin boys given we had a single embryo transfer At the week scan, they asked us if we wanted to know the sex of our babies and we said we already knew one was a boy and assumed the other was as well Anyway, imagine our surprise when they said one was a girl and one was a boy!!!!!
Can male/female twins ever be identical? This is due to the twins not sharing the same DNA like identical twins and are physically different in appearance Fraternal twins occur when there are two separate eggs which are fertilised by two separate sperm cells With fraternal twins you can have either two girls, two boys or boy and a girl combinationsIn 999% of cases boy/girl twins are nonidentical However, in some extremely rare cases resulting from a genetic mutation, identical twins from an egg and sperm which began as male (XY) can develop into a male / female pair
Fraternal twins will not be identical and can be either the same sex or a boy and a girl Identical twins This is when only one egg is fertilized, and the zygote splits into two early in pregnancy, forming two embryos Identical twins have the same chromosomes, and will look the same and be the same sex Implantation in the womb Semiidentical twins statistics Semiidentical twins are extremely rare Only two cases have been reported so far A set of twins from the US was reported in 07 and a case of 4year old boygirl twins in Australia was reported in 19 In the last case the twins shared a placenta during pregnancy Twins are two offspring produced by the same pregnancy They can be either identical twins, meaning that they develop from one egg (monozygote), which splits and forms two embryos, or fraternal
It seems like it should not be possible, but a recent case showed that sometimes a boy and a girl are born as semiidentical twins An ultrasound of identical twins Credit ItActually, there can be identical boy/girl twins if the sex gene of the embryo has an extra x chromosome (the fertilized egg would be an xxy) then when the egg splits one can have xx (girl) genes and one can have xy (boy) genes Rare but possible*The rare instance in which a set of boy/girl monozygotic/identical twins occurs is the result of Turner's Syndrome, in which both individuals are actually XY boys, but one child loses the Y chromosome, yielding a baby who is XO One twin appears externally to be a girl, but grows up infertile, short, and usually with a couple of other
#BodyBizarre #BornDifferent #ConjoinedTwinsCan conjoined twins be a boy and a girl?So far, all the conjoined twins featured in our channel are whether two bo Is it possible for a boy girl pair of twins to be genetically identical? There is a genetic mutation that can occur in male identical twins before they're born which results in one of the twins losing a male chromosome and developing as a female However, even as an identical twin (male), I agree that it is stupid to ask boy/girl twins this question because of how rare it is for that genetic mutation to occur
The two girls started out like all identical twins, developing from the same fertilized egg and the exact same set of DNA But when they were born last year they didn't look like identical twins One girl has peach skin and blue eyesIn today's video, you'll watch us #SWITCHPLACES and try to trick our friends, including Bailey's boyfriend, Asa! The twins can be two girls, two boys, or a boy and a girl Identical twins occur when a single fertilized egg splits and develops into two fetuses Identical twins might share a placenta and an amniotic sac or the twins might share a placenta and each have separate amniotic sacs Genetically, the two babies are identical
I am an identical twin (and 31 years old), and just found this out about a month ago I was watching a show on the Discovery Health channel that talked about multiples, and how doctors are using the term "monozygotic" rather than "identical" now, because an egg can split and become one boy and one girl! Rarely, a boy and girl may be identical twins This condition, called Turner Syndrome, afflicts very few pairs of twins The gender difference occurs when an egg and a sperm pair that begins as two males, loses a copy of its dominant Y chromosome when it splits A twin boy and girl may be identical, according to a study found on NCBI, although this situation is very rare yes Same sex di/di twins can be identical When the embryo splits in the first few days, each baby will have its own placenta and amniotic sacIe Di/di identical twins
Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into 2 If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA A boy has XY chromosomes and a girl has XX chromosomesFraternal triplets are more common than identical or monozygotic triplets Around 80% or more of triplets are the fraternal variety This is largely because most of the factors which influence other multiple births (such as twins), which still play a part in conceiving non identical triplets Doctors in Australia say they have identified a second case of twins apparently created from one egg and two sperm, a boygirl combination in whom the mother's DNA is identical in both babies but
The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births And while it may be obvious, identical twins are always the same sex, either both boys or both girls, at birth Is it possible to have identical twins of different genders? More types of twins exist than previously thought Beyond identical and fraternal, there's a rare third type Twin pregnancies have unique risks and outlooksThere's no such thing as identical boy/girl twins Identical means that they have the same DNA Gender is in the DNA A boy can't have the same DNA as a girl because the boy's DNA would show that he was male and the girl's would show that she is female
Boy/girl monozygotic (identical) twins DOCTORS say they have discovered the world's second known case of semiidentical twins born from one egg and two sperm The now fouryearold boy and girl, from Brisbane, Australia, are identicalIdentical (monozygotic) twins are always of the same sex because they form from a single zygote (fertilized egg) that contains either male (XY) or female (XX) sex chromosomes A set of boy/girl twins can only be fraternal (dizygotic) Boy/girl twins cannot be identical (monozygotic) Click to see full answer In this regard, can a boy and girl twin be in the same sac?
