Can twins have babies together?

"Twins married to twins who both have babies at the same time." Since identical twins share the same DNA, the children of two pairs of identical twins are legally cousins, but genetically more similar to siblings. The sisters shared they had both discussed the possibility of quaternary twins.

What would happen if a twin brother and sister had a baby?

If these twins happened to have children together, the child will indeed share 100% DNA with it's parents and siblings. However, such cases are extremely rare. It happens when: The egg contains two X chromosomes and was fertilized by a Y sperm, creating an XXY zygote.

Can twins get each other pregnant?

Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart. Superfetation is observed in animal reproduction, but it is exceedingly rare in humans. Only a few cases are documented in medical literature.

Can two twins have twins?

According to The American Society for Reproductive Medicine, women who are fraternal twins have a 1 in 60 chance of having twins, and men who are fraternal twins have a 1 in 125 chance of fathering twins. It was previously believed that identical (monozygotic) twins were random — not genetic.

Can twins reproduce?

Fraternal or 'dizygotic' twins

Two separate eggs (ova) are fertilised by two separate sperm, resulting in fraternal or 'dizygotic' (two-cell) twins. These babies will be no more alike than siblings born at separate times. The babies can be either the same sex or different sexes, with the odds roughly equal for each.

Can a girl get pregnant by another girl?

Two cisgender women (meaning assigned female at birth) in a relationship cannot become pregnant without some form of assisted reproductive technology (ART). The reasoning goes back to basic biology and how an embryo is formed. To create an embryo, a sperm cell and egg cell must meet in some way.
