Table 2. Linkage equilibrium among T. annulata populations in Oman and comparison of parasites in Oman, Tunisia and Turkey.
| IA S | VD | LMC | LPARA | Linkage | |
|---|---|---|---|---|---|
| Oman | 0.019 | 1.4595 | 1.29 | 1.29 | LD |
| Batinah | -0.0131 | 1.0344 | 1.4076 | 1.3806 | LE |
| Dhira | 0.0219 | 1.5537 | 1.4509 | 1.4378 | LD |
| Dhofar | 0.0231 | 1.7435 | 1.5167 | 1.5129 | LD |
| Sharqia | 0.0337 | 1.5627 | 1.4451 | 1.4342 | LD |
| Oman, Tunisia & Turkey | 0.0238 | 1.1099 | 0.9317 | 0.9312 | LD |
| Oman & Tunisia | 0.0224 | 1.1846 | 1.0075 | 1.0092 | LD |
| Oman & Turkey | 0.0238 | 1.1099 | 0.9309 | 0.9312 | LD |
To test the hypothesis of geographical sub-structuring, the IS A, VD and L values were calculated separately for samples in each region. The IS A value for Dhira, Sharqia and Dhofar was 0.0219, 0.0337 and 0.023, respectively. The VD values were greater than the L value, indicating LD in all regions (Dhira, Sharqia and Dhofar) except Batinah.
