12 Comedians Who Died Before Their Time. by Patrick Bromley. Updated March 18, 2017. There are comics who work for decades and never produce anything of value, and then there are comics who are brilliant but die tragically before the world really has a chance to see the full extent of what they really could have done.
Your autosomal DNA is a random subset of your mother's and father's DNA (50% from each parent). Two siblings will not have the same results for the same reason that they do not look exactly the same. They do not get the exact same 50% from each parent. Even identical twins don't have exactly the same DNA (only almost exactly the same).
First, share your profile with your sibling(s) from the Manage Sharing page. Then compare your genome to that of your sibling(s) using the Family Traits feature. Full siblings will have some fully identical regions (dark blue) and some half-identical (light-blue) regions. Half siblings will only have some half-identical (light-blue) regions. This feature locates other 23andMe members that match your DNA. We sort people into likely relationships based on how much DNA is shared. When two people share identical segments of DNA, this indicates that they share a recent common ancestor.
