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).
Identical twins have exactly the same DNA. They will be the same sex and they are more likely to look like each other. Fraternal or non-identical twins develop from two separate fertilized eggs. Non-identical twins will share on average half of their DNA, similar to the percentage of DNA shared by two siblings who are not twins. Fraternal twins can be the same or different genders.
