Table 2 Statistics and genetic variance parameters of the GGC trinucleotide in the androgen receptor (AR) gene in 13 populations. Absolute and relative (in parentheses) repeat frequencies are grouped into alleles of less than 15 repeats, alleles of 15 to 17 repeats, and alleles of more than 17 repeats
