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 twinsAnswer (1 of 6) 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 This But at 14 weeks of pregnancy, tests revealed the twins were nonidentical – one was a girl and the other a boy Ordinarily nonidentical twins would have their own placenta They were an anomaly Thorough DNA testing has revealed they are identical on the maternal side (confirming they came from just one egg, like identical twins)
But at 14 weeks of pregnancy, tests revealed the twins were nonidentical – one was a girl and the other a boy Ordinarily nonidentical twins would have their own placenta They were an anomalyIn 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 This happens when the fertilised egg 'loses' one of the copies of the Y chromosome when it is dividing into two Trevor Smith/E/Getty Images 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,
Everyone has the same chance of having identical twins about 1 in 250 Identical twins do not run in families But there are some factors that make having nonidentical twins more likely nonidentical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese There are more than two types of twins Think there are only fraternal and identical twins?

The chance of having twins is just about 3 in 100, so that is roughly a 3% chance of conceiving twins at any given timeHowever, with semiidentical twins, it is even rarer It is estimated that 999% of identical twins Healy says if twins are identical, they come from a single egg that splits, which means they're "monozygotic" The twins can be two girls, two boys, or a boy and a girl As a result, the chances of fraternal twins resulting in boys, girls, or a combination are the same as for any other pair of siblings Monozygotic twins, on the other hand, are always the same gender, either two girls or two boys Fraternal Twins (Dizygotic) Come from their own egg and sperm Share about 50% of DNA
This is barely more than the usual assumption of 50%, which makes sense because identical twins are rare Compare this to the fact that the ratio of boys to girls at birth is not 11, but about 1051, so that about 512% of babies are boys Twins have less effect on the ratios than other causes Post navigationBecause fraternal twins (nonidentical) are just like any other siblings Their genders have no Identical twins are born together, and look exactly alikeNonidentical twins are born together, but do not look exactly alikeA good example of non identical would be boy and girl twins,
What are the chances of having boy and girl semiidentical twins? In 999% of cases boy/girl twins are nonidenticalHowever, 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 pairDizygotic Twins are more common than identical twins The most common is boy/girl twins which makes up nearly half of all twins born, about 40% In total nonidentical twins including fraternal girl/girl and boy/boy twins make up about 75% of all twin births Next in order of most to least common are fraternal girls, fraternal boys, identical girls then identical boys
While those are certainly the most common, there are actually other types of twin babiesYou could have mirror image twins, for example — identical twins from an egg that has split into two later than usual — who have "mirror image" birthmarks and traits (the same ones
