Table 2. Comparisons of the frequencies of short ANs, large ANs and 22 CAG normal alleles in the short, normal or large genotypes.
| Counts (frequency of alleles) | ||||
|---|---|---|---|---|
| Genotypes (n) | Short ANs | Large ANs | 22 CAG | Total (2n) |
| Short heterozygotes (57) | 78 (0.68)a | 16 (0.14) | 20 (0.17) | 114 |
| Large heterozygotes(286) | 16 (0.02) | 356 (0.62)b | 200 (0.34)c | 572 |
a
χ2=288.46, d.f.=1, P=0.0000 (short ANs in short heterozygote group vs short ANs in large heterozygote group).
b
χ2=288.46, d.f.=1, P=0.0000 (large ANs in large heterozygote group vs large ANs in short heterozygote group).
c
χ2=13.24, d.f.=1, P=0.0003 (22 CAG ANs in each large or short heterozygote groups).
