Mar 26, 2020 · An interactive version of the shared cM data with probabilities showing the most likely relationships

Apr 6, 2020 · One of the most common cases of DNA test confusion comes from a measuring unit in your DNA called the centimorgan. Understanding what centimorgans are and viewing how they are measured on a centimorgan chart can help you make sense of your DNA results.

Dec 3, 2024 · To use the centimorgan relationship chart, you’ll need the number of centimorgans you share with someone (e.g., 2754 cMs). Once you have that number, you can look it up on the Bettinger DNA cM chart to predict your relationship.

As of April of 2022, this tool includes probabilities generated from data that include X-DNA, a first for genetic genealogy tools. For probabilities at any other site, it's important to subtract X-DNA off of the total. The X-DNA amount can be significant: several relationship types share up to 182 cMs of X-DNA and full-sisters share up to 364 cMs.

Nov 21, 2024 · Hopefully this online tool will help you learn about your DNA matches and their relationships to you. Just enter a centimorgan number, choose a generation and press "Show Relationships." If you need additional help or notice any problems with the …

Aug 15, 2016 · They do not seem to take segment sizes into account, rather they primarily use total shared DNA measured in centimorgans (cMs) for their relatedness estimates, usually the sum of all matching segments of 5 cM or larger.

In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. It is often used to infer distance along a ...

Aug 4, 2024 · As I mentioned above, cM in DNA stands for “centimorgan, and a centimorgan measures genetic distance, typically between two points on a chromosome. When two people have identical DNA between two points on a chromosome, we call this an identical DNA segment.

May 8, 2024 · In this beginner’s guide to shared centimorgans, learn all about DNA segments and how to estimate your relationship with your DNA match using shared centimorgans. I’ll answer questions like “what is a centimorgan?”, and more! In this article, find out:

Jul 10, 2023 · It's the centimorgan (cM) number that really matters. This number tells you how much DNA you have in common with another person. Another factor that's important is what generation you are in compared to your DNA match.
