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.
Here is my full sister and how much DNA I share with her as well as the number of segments that we have in common. Siblings are expected to share about 50% of their DNA --- my sister and I share slightly more than expected, just by random chance. Getting your siblings tested at 23andme is very useful because they will have DNA (and relatives along that DNA) that you do not have.
