a riddle for you from high school biology class?

[heavenlyhope777]

There are two girls

they were born on the same day, same month , and same year
they were born from the same mother and came from the same womb, yet they are not twins? how can this be?

[Raleigh]

They are a pair from triplets.

[bekky]

concieved at different times.

[C. J.]

Invitro fertilization. Two different eggs fertilized at different times and implanted into the mother's womb.

[*shrug*]

if the mother donated the eggs, then it would be possible

[nickelrustler]

They are not human...ie dogs, cats, etc

[Elliot]

They're triplets. Or two members of some larger multiple birth.

Theoretically it's possible that they have different fathers, but the process by which that would happen is extraordinarily unlikely.

[Ashleyy :]]

[Erika J]
