The DYS710 marker is a high frequency mutating YSTR that is very useful for near range (family) genealogy studies. Many alleles carry a N.2 micro-allele which further increases the variability of this marker. I just have fixed the bug in Ymatch which prevented entering the micro-allele, so you are able now to store the allele with- or without a microallele in your DNA-Fingerprint account.
Here is a frequency distribution chart for the first 142 results.
The marker can be ordered from Family Tree DNA in the advanced orders panel.
