Table 1.
Number of putatively homologous tag pairs between subgenomes within linkage maps of diploid, tetraploid and hexaploid oats.
| A. strigosa x A. wiestii (2n = 2 × = 14) | A. barbata (2n = 4 × = 28) | Totalsa | ||
|---|---|---|---|---|

| A genome | NA (NA) | 2420/815 (0.1114) | 155/342 (0.0251) | 22018 |

| A genome | 417/337 (0.0396) | 619/494 (0.0427) | 79/173 (0.0149) | 16042 |
| D genome | 188/270 (0.0215) | 222/432 (0.0231) | 90/197 (0.0150) | 20572 |

The number of putative homologies is indicated separately for exact sequence matches, and for pairs showing 1–3 bp mismatches. Dice similarities, which account for the different number of tags in each genome are given in brackets.
aTotal number of markers from each subgenome. Thus, for example, out of a total of 22018 mapped tags in the A. strigosa x A. wiestii mapping population, and 36075 tags mapped to the A genome of A. barbata, 2420 identical tags and 815 pairs showing 1–3 base mismatches were observed. This gives a total of 3235 putatively homologous tags for a Dice similarity of 0.1114.
