Sort Your Chart Cellsįirst, you can put your color clusters in traditional order of a genealogy tree: dad’s dad, dad’s mom, mom’s dad, and mom’s mom. Sanger’s Method: The first DNA sequencing method devised by Sanger and Coulson in 1975 was called plus and minus sequencing that utilized E. When working with 2nd and 3rd cousins, you can label your columns by both your “4 GRANDS” (4 grandparents) and “8 GREATS” (8 great grandparents). Since our DNA is a double helix, it means that there are two strands composed of many nucleotides.

These four bases are used to encode the different genes, proteins, regulators, and everything else that our DNA is used for. If your chart gets too “busy” looking, hide any columns you do not currently need. There are four bases in our DNA: adenine (A), guanine (G), cytosine (C), and thiamine (T). If the relationship is unknown, use a question mark. Then, write the relationship in shorthand: “C” for cousin “R” for removed. If the relationship is known, make sure the number of centimorgans makes sense. You can put this number in a separate column, as in this example, or write the number on the colored cells. Number of Centimorgans (cM)Ĭentimorgans, or cM, is how we measure how much DNA we share with our DNA relatives.

Name in RED font? These are the people with an unknown relationship. Name in BLACK font? These are the people whose relationship is known. When you first enter your list of 2nd & 3rd cousins using the Leeds Method, add a column for “sequence number” so you can always “unsort” your chart and get your matches back in their original order when needed.
