This is a tool designed to be a visual aid only. It does not automatically build your family tree or provide definitive proof of any relationship. Instead, it displays a grid of suggested positions for your DNA matches relative to you (“SELF”) based on the cM values of the matches from your DNA test. Use […]
I have setup a Facebook Group so that anyone interested, or that happens across this website while I am still building it join and ask questions of hints for things to add to the Relationship Grid page. https://www.facebook.com/groups/dnamatch
This table shows the current cM parameters that the Relationship Grid is using to place matches within the cells, these cM values at some levels have been raised from the original 0cM level which they are listed by the “Shared cM Project” I decided to do this so that the lower minimum value or Maximum […]
“Pedigree collapse” occurs in genealogy when an individual’s ancestors appear in their family tree more than once, typically because the ancestors are related to each other, either distantly or closely. This phenomenon is also known as inbreeding or consanguinity when referring to closer relationships. In simple terms, it happens when the same ancestors are found […]
This project is essentially an extension of the Shared cM Project, but it specifically focuses on more complex familial relationships and genetic phenomena. Here’s a breakdown of the key components: Pedigree Collapse: In an idealized family tree, you’d expect an exponential increase in the number of ancestors as you go back each generation. However, due […]
