If they do both release and a guy does the y'know can a sperm penetrate both eggs and what happens with that? |
Yep it could happen and they would be fraternal (non identical twins) and in essence it can happen on different days. Eggs are only viable for fertilisation for 24 hours but sperm are viable for longer (up to 72 hours) so if two eggs are released 48 hours apart they could theoretically both fertilise and implant.
