It's been a while since I took biology, but doesn't this depend on the genders of the siblings?
Two male brothers have XY, and the Y would have to be shared with the father, and same with two sisters (X from father), but a brother and sister would get a minimum of 50% different as the X and Y from the father would be different?
- mbreese 5y agoIn humans, y is so small as to be insignificant in these terms. ChrX is much larger. Also, the combination of the remaining chr1-22 are much larger than chrX by itself, so these numbers don’t factor in as much as you’d think. Rough scale example: XXXXXXXXXXXXXXXXXXXXXXX YY
