Figure 2.
Complex intergenic recombination patterns between fragments of the env, gag and pol genes (modified from Hayward and Rodrigo, 2008). Lines link sequences isolated from the same host, to highlight incongruities in subtype assignment between the different gene regions. The three thickened lines show the significant intergenic recombinant sequences, as determined by the SH test (Shimodaira and Hasegawa, 1999) (see Hayward and Rodrigo, 2008). Reference sequences are FIV-C36 (subtype C; AY600517), Petaluma (subtype A; M25381), TM2 (subtype B; M59418).
