Identical twins come from a single fertilized egg that splits into two. Both parts of the fertilized egg implant in the uterus and each produces one of the twins. Can identical twins be male and female? 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.   in very rare cases, identical twins can be different sexes. Like all males, they both have xy sex chromosomes, instead of xx like all females do.   twins are when two children are produced in the same pregnancy. They can be identical or different, and two boys, two girls, or a girl and a boy.   well its important to know right from the outset that recent scientific studies have shown that identical twins may not actually have exactly the same genetic code due to what are known as copy number variants. However, dizygotic twins may also look very different from each other (for example, be of opposite sexes). Studies show that there is a genetic proclivity for dizygotic twinning. However, it is only the mother who has any effect on the chances of having such twins there is no known mechanism for a father to cause the release of more than one. Fraternal twins are born from two different eggs and two different sperm cells, identical twins are born from one egg fertilized by one sperm cell, which splits in the growth process asked in snakes. However, it is possible for monozygotic twins to be opposite sexes if a mutation occured in one twin. The birth of fraternal twins can present a unique set of blessings and challenges parents. The majority of the twins are going to be fraternal twins, which means that there were two eggs that were fertilized.
