Pros of hiring an architect. 1  You, as the owner, have an agent to keep an eye on the contractor and workmanship throughout the project. The architect has a fiduciary responsibility to the owner (under a full service contract). 2  Better design.
Converting centiMorgans into percentages. In order to get an approximate percentage of shared DNA from a Family Tree DNA Family Finder test, take all of the segments above 5 cM, add them together and then divide by 68. The way the calculation works is that your total genome in cMs with the Family Finder test is 6770 cM.
If I get the question right, the answer is 6.25%, not 25% as the other answer says. Its easy to calculate. Siblings share 50% of DNA on average, it also doesn't deviate much from it as the shared HIR (half identical regions) are very long and can sometimes cover the whole chromosome. There are also the least amount of recombinations within one generation. Half siblings have half of that, as the name says, so 25%.
