- allele
The scientific result for a marker, shown as a number. - The laboratory examines the DNA sample and uses standardized protocols to count the number of repeats of genetic patterns at standardized locations on the DNA helix. A yDNA result is the number of times a specific pattern repeats (alleles) at particular addresses (markers). People usually just say the number of alleles they got at a particular DYS#, as in “I got a 10 at 391”.
