Assuming that:
1.The fathers aren't related
2. Born the same time(hour/day/year)
**Please leave any negative cultural assumptions out as much as possible I want to know this merely from a scientific view point**
I know the children might not have the same exact DNA or parents for that matter so some might say they aren't twins. However, children,(not identical) who's birth meet the criteria in my #1 assumption are considered twins but siblings that are several years apart are not. Why is that?. I mean they have the same parents right?This led me to the conclusion that timing of births figures greatly into whether or not a set of siblings are considered twins. (another way of determining a set of twins) So, I'm asking, because the kids in my question situation meet the timing aspect but not DNA(like fraternal twins) would they be considered twins?
*If you see any errors in my line of thinking please feel free to straighten it out. I won't take offense, cuz I'm here to learn*
