The birth of extremely rare semi-identical, or sesquizygotic, twins has been reported in Brisbane, Australia. Twins are typically either monozygotic or dizygotic. In a monozygotic case, a single sperm fertilises a single egg, which divides to create ‘identical’ twins of the same gender, who share all of their DNA.

What are polar body twins?

Fraternal twinsFraternal twins are the most common type of twin, with around 40% of all twins born being boy-girl combination fraternal twins.
Who carries the twin gene?
The quick answer to this question is that, in a twin pregnancy, it is the mother’s genes that determine twins. First up, giving birth to identical twins is not genetic, but conceiving fraternal twins is. The mother may have the genetic trait of releasing two eggs in one menstrual cycle.
Can twins be conceived on different days?
Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart. … Superfetation is suspected only when the twins are of different sizes and at different stages of development. It is typically noticed during a routine checkup on the ultrasound.
