Allele frequencies of the Y chromosome-specific short tandem repeat sy
stem DYS19 (Y-27H39) were determined from blood samples obtained from
251 unrelated Japanese in Fukui and Gunma Prefectures. Five alleles th
at contained 10, 11, 12, 13 and 14 repeats of GATA were detected, Alle
le frequency distributions in Japanese populations were different from
those in other Asian and Caucasian populations.
