From the standpoint of eugenics and biology, brothers and sisters bear a closer relationship to one another than they do to either of their parents.
That makes complete sense. Each parent comes from a separate genetic line but their children blend those two together.
Imagine mom having A and B in her and dad having C and D. While you could have any mixture of A, B, C, and D either parent will still have only A and B or C and D. Your sibling will also have a mixture of A, B, C, and D, therefore being closer in structure to you.
Can you tell I was a science nerd for a long time?
Okay, if that's the case, would a half sibling be closer than their parent biologically speaking?
Is that possible, if you have the same parents?
I suppose it would depend on the genetic makeup of each parent? Like if the Mom of one was AB, and the Dad from the previous relationship was AB, then they wouldn't be as close if the Mom married a CD, would they?
I would think so. Half siblings would have EF/GH in them, if you followed me earlier.
Wow! Thank you for breaking it down for me.. I was never good at that kind of science AT ALL! You rule. It's so simple, but I never would have made that connection...
