“Well the liklihood would be half of what Steven’s was of having a gem so I’m assuming that would equal out to be 50% or 25% depending on whether Steven’s chances were 100% or 50%. Genetics would imply the Steven had a 50% since Greg is human but from what I’ve been told Rose knew Steven would get her gem so that makes me think it was 100%.” Rai explained trying to figure t out as she went.
“So if there’s a 50% chance of each of them having gems, there would 25% chance of all three having gems?” Pearl asked.
“That would be the case if two of them weren’t identical.” Rai said and seeing everyone’s confusion explained further. “The way identicals work is they come from a single fertilized egg that splits into two. Basically I was originally expecting non-identical, or fraternal, twins and when the egg split it became triplets. Since they’re identical, they’re either both going to have a gem or neither will. It’ll be impossible for one to have a gem and the other not to. Granted there is something called half-identical twins where the egg splits before being fertilized and is then fertilized by two different sperm cells causing them to share 50% of their DNA whereas identical twins share 100% and fraternal twins and siblings in general share about 25%, however the existence of half-identical twins is just a theory and hasn’t been proven or disproven for that matter. Regardless that all means the chances of all three having gems will be higher than 25% at 50%, which is also the percentage of all three being a single gender. When it comes to gender there’s actually a 25% of all boys, 25% of all girls, 25% of one boy and two girls, and 25% of two boys and one girl.”
