Just a random question


Recommended Posts

I am a student, and I really like to know random facts. So I just wanted to ask, if any one here could answer. Is it actually possible in real life that a father of identical twins have an identical twin, I suppose yes, but does this give any genetic problems? And if it's possible, then witch is the probability of this happening in our world? Note: Fraternal twins and identical twins are not the same. Картинки по запросу "fraternal twins"

As I understand it, IDENTICAL twins do not run in a family.  That's always the way it's shown in fiction, because those are the immediately-obvious kind of twin and make a good visual, but as far as I know it's random that a fertilised egg will split that way.

HowEVer...there is one type of twin that _can_ legit run in families:  Fraternal twins.  Why?  Because the tendency to release more than one egg per cycle CAN be genetic.  It can be passed down from mother to daughter (or skip generations occasionally).  That _is_ a thing that can run in families. 

So sadly no, the cool kind of obvious twins cannot be passed down, nor can it ever come from a (cis) male family member.  You can't inherit the tendency to have twins of any kind from your dad or uncle (unless he's a trans-male, like my own second cousin for example) nor can you inherit the tendency to have identical twins at all.  But if you're a girl and you are a fraternal twin yourself, or your mom or aunt is, and you find out you're pregnant...you MIGHT wanna buy extra diapers, just in case.  ;)

And this for the answer to:  "What if William and Jack both got together with one each of twin sisters, too...?" which I've been seeing some people wonder in other threads.  : P

Sci-Show is awesome, yo.  :)
