Enter the total centimorgans (CM) shared and the number of segments into the calculator to determine your estimated relationship.
CM DNA Calculation Formula
The following formula is used to calculate the estimated relationship based on CM shared.
Relationship Estimation = Total CM / Number of Segments
Variables:
- Total CM is the total centimorgans shared between two individuals
- Number of Segments is the number of DNA segments shared
- Relationship Estimation is the estimated relationship in CM per segment
To calculate the estimated relationship, divide the total CM by the number of segments shared. This will give you an estimate of the CM shared per segment, which helps in determining the closeness of the relationship.
What is CM DNA Calculation?
CM DNA calculation refers to the process of determining the estimated relationship between two individuals based on the amount of DNA they share. Centimorgans (CM) are a unit of measure for the length of DNA segments shared between two people. The more centimorgans shared, the closer the relationship is likely to be.
How to Calculate Relationship Using CM DNA?
The following steps outline how to calculate the relationship using CM DNA:
- First, determine the total centimorgans shared between the individuals.
- Next, determine the number of DNA segments shared.
- Use the formula from above: Relationship Estimation = Total CM / Number of Segments.
- Calculate the relationship estimation by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Total CM Shared = 2500 CM
Number of Segments = 50
Relationship Estimation = 2500 / 50 = 50 CM per segment
