What is a genetic distance of 1 mean?

Genetic distance is determined by the number of differences in the count of repeats of the marker or markers that did not match. A genetic distance of one means the marker which did not match was only one repeat away from being a match.

What is a genetic distance of 6?

What does a genetic distance of 0 mean?

A genetic distance of zero means there are no differences in the results being compared against one another, i.e., an exact match. This is the meaning when comparing Y-chromosome DNA or mitochondrial DNA. For autosomal DNA comparisons, genetic distance may refer to the size of a DNA segment.
