i know someone who was so desperate to have just twins she had ivf (and she is under 30) just for it where they inserted two eggs. now she has non-idential boy and girl.
if you have the money, you can do that! lol!
boy girl twins are not identical..
only way that can happen is due to a rare situation called the turner effect
and it has serious issues.
My husband has a twin sister…so im hoping i may have a chance to have twins…but then people say that it skips a generation…my husbands dad had twin brothers…and his mum ended up having him and his sister…so heres hoping
Get it out of the way in one time
answer below..
when people say fraternal twins skip a generation its cuz a guy who has a twin sister is not ovulating.
but his daughters could have fraternal twins because err well they would be ovulating..
okay birds and bees time
so fraternal twins are born when the chica has multiple eggs that month..it can be natural i.e. genetic or via fertility drugs usually make the lady have more than one eggs in that priod, a la octomom.
so all the man and his role is that the sperm go and fertilize 2 eggs ..or 8 as was the case of octomom.
so it is genetic for fraternal twins but since the man is not ovulating, his genes dont matter here.
so where do his genes matter, his daughters…so even if there is no twins on the mothers side, and lets say they have a daughter. This daughter can have fraternal twins.
next we have identical twins, where there is a single egg, and a single lucky sperm out of the many who make the trip…yaaay sperm..good job.
anyways, so something causes the fertilized egg to split, well its not an egg anymore but you get the idea. what determines that? now here there is no real proof and many scientists say that its random, however I think there is more to it because some families seem to have identical twins and some dont
