This is rarely true, you share 50% of your genes with your mother an father each, but you can theoretically share anything from 0%-100% (Probably normal distribution curve), since your mother/father has 46 (23 pairs) chromosomes and you receive a single random chromosome from each pair (total 23 singles), that are then paired with 23 singles from your father/mother.
For a given rare genetic difference from the population at large, you have roughly 50% chance of sharing it with your sibling, a child of yours, or a given parent of yours. Absent some sort of green-beard effect, the effect of selection on each will be approximately the same and thus (getting poetic) similarly guide the hand of the Alien God.
Yes I agree and that was not something I was disputing. From one gene’s point of view there is a 50-50 probability that your sibling carries that exact same gene.
I only pointed out: That you do not always (or even often) share 50 % of ALL your siblings genes. Edit: (From an organisms point of view)

Note that I have not taken Chromosomal crossover into account.

For sure.
