What does cm mean in DNA results?

The abbreviation cm refers to the amount of DNA in one copy of a chromosome The average amount of DNA in a chromosome is about 23.3 centimeters. There are 22 pairs of chromosomes in humans, so the total amount of human DNA is about 23.3 x 22 = 5.2 billion base pairs. That's about one gene on each chromosome.

What does centimorgan mean in DNA results?

A centimorgan is a term that refers to a measurement of a change in the length of a chromosome. Typically, a change in the length of a chromosome is called an allele. The length of a chromosome is dependent on the number of base pairs it contains.

What does cm mean in mtDNA?

The most commonly used unit in mtDNA analysis is the mutation rate per site. This is the number of times a single mutation occurs on average at a single nucleotide site in your mtDNA nucleus. This mutation rate varies among different populations and lineages and is important for calculating the mutation age of a genetic lineage. The mutation rate for the entire mtDNA molecule is generally around 1.5 mutations per site per million years. This rate can vary depending on the population you have data for.

What does c.m mean in DNA results?

This abbreviation stands for count of mutations (or mutations per megabase). It's quite easy to calculate the number of c.m. in which your DNA has changed. You can do so based on your SNP results. SNP results are determined by counting the number of nucleotides in which you have two different alleles. The mutation count can be obtained by multiplying the number of SNPs found by the number of nucleotides per chromosome.

What does cm mean in your DNA test?

Cm refers to the length of a chromosome. If you have a genome that is 20cm long, then that chromosome would be 20 centimers long. This is usually written as 20c. For comparison, one centimeter equals 0.4 inches.
