Table 1 Statistics and genetic variance parameters of the CAG trinucleotide in the androgen receptor (AR) gene in 13 populations. Absolute and relative (in parentheses) repeat frequencies are grouped into alleles of less than 19 repeats, alleles of 19 to 21 repeats, and alleles of more than 21 repeats. n Number of gene copies (chromosomes), H heterozygosities; no. alleles number of different alleles
